Over the past 3 years, colorectal surgeons have begun to adapt the technique of transanal total mesorectal excision. As international experience has been quickly forged, an improved recognition of the pitfalls and the practical details of this disruptive technique have been realized. The purpose of this technical note was to express the various nuances of transanal total mesorectal excision as learned during the course of its clinical application and international teaching, so as to rapidly communicate and share important insights with other surgeons who are in the early adoption phase of this approach. The technical points specific to transanal total mesorectal excision are addressed herein. When correctly applied, these will likely improve the quality of surgery and decrease morbidity attributable to inexperience with the transanal approach to total mesorectal excision.

This study was designed to assess the gross morphometric studies of the tongue, hard palate and buccal cavity of the fruit bat (Eidolon helvum). Sixty bats of both sexes were used for this study. The tongue was excised, and the weight and various linear measurements were determined. Linear measurements were also determined on the hard palate. The gross distribution of the lingual papillae was observed to be the same in both sexes; values obtained for the weight and length of the tongue were higher in the females, although no statistically significant differences were observed (P > 0.05). The number of ridges on the hard palate displayed sexual dimorphism. Results obtained from this study may find application in the field of comparative and clinical anatomy of wildlife and also in feeding physiology. © 2014 Blackwell Verlag GmbH.

Awake Intradural Spinal Tumor Resection; Case Report and Literature Review.

Meningioma is a common slow-growing spinal tumor with a predilection for intradural occurrence. Patients usually present with pain followed by ataxia and sensory and sphincter problems. The gold standard treatment in these cases is gross total microsurgical resection under general anesthesia. However, there exist high-anesthetic-risk patients unsuitable for general anesthesia. Performing spinal surgeries under local anesthesia and sedation has been reported, albeit rarely for mostly minimally invasive procedures but not for open intradural pathologies. We report a 63-year-old woman with critical aortic stenosis, coronary artery disease, and severe chronic obstructive airways disease who presented with 10 months' history of worsening back pain and bilateral leg pain, ataxia, hyperreflexia in lower limbs, as well as altered lower limb sensation. Magnetic resonance imaging revealed a contrast-enhancing intradural lesion at T6/7 with severe spinal cord compression. However, the patient was American Society of Anesthesiologists class IV and her cardiac disease was not amenable to intervention. She underwent thoracic laminectomy and excision of the tumor under local anesthesia and sedation with no significant complications and clinical improvement. Our illustrative case and literature review suggest that using local anesthesia and sedation to perform spinal surgeries including intradural tumors is possible even in high-risk patients with good outcome. Our American Society of Anesthesiologists class IV patient tolerated the surgery well with gross total tumor resection and subsequent resolution of the symptoms. Copyright © 2018 Elsevier Inc.

Hereditary multiple exostoses (HME) patients frequently present with ankle valgus deformity and marked fibular shortening. Loss of the lateral buttress may cause translational talus instability (TTI) that manifests as ankle pain after physical exercise, medial clear space widening on plain radiographs, and gross translational movement of the talus within the mortise. Among 123 HME patients examined and/or surgically treated, 10 patients (14 ankles) with symptomatic TTI underwent fibular lengthening with osteochondroma excision. Twelve ankles of 9 patients were followed for >1 year after surgery. Total fibular length gain averaged 15.3 mm and distal migration of the distal fibular fragment averaged 5.5 mm. The mean medial clear space decreased from preoperative 6.7 mm to postlengthening 3.5 mm. Gross instability of the talus within the ankle mortise disappeared in all cases. AOFAS ankle-hindfoot score improved from preoperative 80.3 to 97.3 at the latest follow-up. The current study showed the fibular lengthening improved lateral ankle stability by providing lateral buttress on the talus and providing favorable short-term result by ameliorating exercise-induced ankle pain in TTI of HME. The authors carefully conclude that TTI is a rare but potentially disabling condition in HME patients, requiring special attention during follow-up of HME patients. Level IV.

Subependymomas are rare, slow-growing, ependymal neoplasms that commonly occur in the fourth or lateral ventricles. A retrospective study of 6 histologically proven subependymomas was undertaken to analyse their clinicopathological characteristics. There were five male and one female patients ranging in age from 11 to 50 years (mean 35.8 years). All patients were symptomatic at diagnosis. The most common clinical presentations included headache (n=6) and vomiting (n=3). Tumours were located in the lateral ventricle in five cases and in the fourth ventricle in one case. Magnetic resonance imaging detected obstructive hydrocephalus in all cases. Five patients underwent gross total resection and one patient had subtotal excision of the tumour. Histologically, all tumours were characterised by clustering of isomorphic cells arranged against a fibrillary background. Focal cystic degeneration was seen in 5 tumours. During the follow-up period, which ranged between 2 months and 10 years, all patients were symptom-free with no evidence of recurrence.

Although higher taxation of tobacco products is considered the most cost-effective tobacco control policy, its negative impact on low-income groups is one of the arguments used against it. To investigate the impact of current excise taxes and the increases of excise taxes on tobacco and household expenditures by expenditure tertiles, and examine who pays excise taxes in general. Impacts of excise taxes on cigarettes are examined with a budgetary approach. We first estimate the price elasticity of cigarettes by expenditure tertiles using data from the 2003 Turkish Household Expenditure Survey, the most recent data set covering detailed tobacco product information relevant to our analysis. We then conduct a number of simulation analyses by increasing the excise taxes per pack of cigarettes and examine the impacts of these increases on household expenditures. Finally, as excise tax increases, we predict the total excise tax paid by households in different expenditure tertiles and compare the concentration curve of excise tax spending with the Lorenz curve showing the cumulative share of total household expenditures by expenditure tertiles. We estimate the progressivity coefficient that measures the area between the Lorenz and concentration curves. The low-income group is found to be the most sensitive to tax and price increases. It spends a relatively higher share of the household expenditure on cigarettes compared with higher income groups. However, the results suggest a different outcome as excise tax increases; the share of household expenditures spent on cigarettes declines for all household tertiles but a significant reduction occurs on the lowest expenditure tertile, suggesting that increases in excise taxes are progressive. Furthermore, the highest expenditure tertile pays the highest excise tax among expenditure tertiles, and their share in total excise revenue increases as the excise tax per pack of cigarettes increases. The poor smoking households benefit the most from increases in excise taxes; from a budgetary perspective, as they reduce their smoking consumption significantly, the share of their excise payment in total household expenditures declines. From a health perspective, they are likely to have more health benefits as their consumption reduces. Government revenues are also predicted to increase with increased excise taxes, and the government can allocate a part of these revenue increases on implementing and enforcing other tobacco control measures including cessation support and smoke-free environments.

2011-01-01

Fibrolipomatous hamartoma of nerves without macrodactyly is a rare lesion characterized by fibrofatty proliferation causing epineural and perineural fibrosis with fatty infiltration around the nerve bundles. We report an unusual case of fibromatous hamartoma of the ulnar digital nerve of the thumb in a 43-year-old woman. Magnetic resonance imaging revealed a large fusiform mass along the nerve. The findings were unusual and pathognomonic and included a coaxial cable-like appearance on axial sections and a spaghettilike appearance on coronal sections on both T1- and T2-weighted images; these findings were useful for the diagnosis and preoperative evaluation of this lesion. Surgical exploration revealed a yellow, cordlike mass of the digital nerve enlarged by fat. Gross excision could not be done without extensive damage to the nerve. Therefore, a limited excision with biopsy of the fibrolipomatous tissue around the nerve bundles was performed. The histological appearance was consistent with fibrolipomatous hamartoma. There was no recurrence of the mass and no neurological deficit 3 years after surgery. Some authors have suggested that invasive excision can cause catastrophic sensory or motor deficits because of the extensive fatty infiltration of the nerve fascicles. In conclusion, the recommended treatment for this lesion is limited excision with only biopsy to confirm the diagnosis.

Introduction: Tumors of the central nervous system (CNS) are the second most frequent malignancy of childhood and the most common solid tumor in this age group. CNS tumors represent approximately 17% of all malignancies in the pediatric age range, including adolescents. Glial neoplasms in children account for up to 60% of supratentorial intraaxial tumors. Their histological distribution and prognostic features differ from that of adults. Aims and Objectives: To study clinical and pathological characteristics, and to analyze the outcome using the Engel's classification for seizures, Karnofsky's score during the available follow-up period of minimum 1 year following the surgical and adjuvant therapy of supratentorial intraaxial extraventricular primary pediatric (SIEPP) brain tumors in children equal or less than 18 years. Materials and Methods: The study design is a prospective study done in NIMS from October 2008 to January 2012. All the patients less than 18 years of age operated for SIEPP brain tumors proven histopathologically were included in the study. All the patients with recurrent or residual primary tumors or secondaries were excluded from the study. Post operative CT or magnetic resonance imaging (MRI) is done following surgery. Results and Analysis: There were 2, 8 and 20 patients in the age range of 0-2 years, >2-10 years and 10-18 years, respectively. There were 21 male patients and 9 female patients. Out of 30 patients, 16 had lesion in the temporal lobe, 6 in frontal lobe, 4 in thalamus, 3 in parietal lobe and 1 in occipital lobe. Out of 30 patients, 11 patients had malignant lesions and nineteen patients had benign lesions. Gross total excision could be achieved in 19 patients and subtotal in 11 patients. Seven patients had mortality and four of the remaining 23 patients had increased deficits postoperatively. Remaining 19 patients either improved or remained same. Conclusions: SIEPP brain tumors have male preponderance, occur in 95% of patients in the age range of 7-18 years and have temporal lobe as the most common site of origin. The seizure presentation has good outcome compared to raised intracranial pressure features. The seizure control is quite good irrespective of subtotal or gross total excision in temporal lobe low grade tumors. All PNETs have survival of less than 1 year even with adjuvant chemo and radiotherapy. PMID:25624922

Microbiological sampling of swine carcasses: a comparison of data obtained by swabbing with medical gauze and data collected routinely by excision at Swedish abattoirs.

PubMed

Lindblad, M

2007-09-15

Swab sample data from a 13-month microbiological baseline study of swine carcasses at Swedish abattoirs were combined with excision sample data collected routinely at five abattoirs. The aim was to compare the numbers of total aerobic counts, Enterobacteriaceae, and Escherichia coli, recovered by swabbing four carcass sites with gauze (total area 400 cm2) with those obtained by excision at equivalent sites (total area 20 cm2). The results are considered in relation to the process hygiene criteria that are stated in Commission Regulation (EC) No 2073/2005. These criteria apply only to destructive sampling of total aerobic counts and Enterobacteriaceae, but alternative sampling schemes, as well as alternative indicator organisms such as E. coli, are allowed if equivalent guarantees of food safety can be provided. Swab sampling resulted in higher mean log numbers of total aerobic counts at four of the five abattoirs, compared with excision, and lower or equal standard deviations at all abattoirs. The percentage of swab and excision samples positive for Enterobacteriaceae at the different abattoirs ranged from 68 to 100% and 15 to 24%, respectively. Similarly, the percentages of swab samples that were positive for E. coli were higher than the percentages of positive excision samples (range 52 to 84% and 3 to 14%, respectively). Due to the low percentage of positive excision results, the mean log numbers of Enterobacteriaceae and E. coli were only compared at two and one abattoirs, respectively, using log probability regression to substitute censored observations. Higher mean log numbers of Enterobacteriaceae were recovered by swabbing compared with excision at one abattoir, whereas the numbers of Enterobacteriaceae and E. coli did not differ significantly between sampling methods at one abattoir. This study suggests that the same process hygiene criteria as those stipulated for excision can be used for swabbing with gauze without compromising food safety. For monitoring of low numbers of Enterobacteriaceae and E. coli, like those found on swine carcasses at Swedish abattoirs, the results also show that swabbing of a relatively large area is superior to excision of a smaller area.

Total mesorectal excision is the standard of care for patients with rectal cancer. Pathological evaluation of the quality of the total mesorectal excision specimen is an important prognostic factor that correlates with local recurrence, but is potentially subjective. This study aimed to determine the degree of variation in grading, both between assessors and between fresh and formalin-fixed specimens. Raters included surgeons, pathologists, pathology residents, pathologists' assistants, and pathologists' assistant trainees. Specimens were assessed by up to 6 raters in the fresh state and by 2 raters postfixation. Four parameters were evaluated: mesorectal bulk, surface regularity, defects, and coning. Interrater agreement was measured using ordinal α-values. The study was conducted at a single academic center. The primary outcome was agreement between individuals when grading total mesorectal excision specimens. A total of 37 total mesorectal excision specimens were assessed. Reliability between all raters for fresh specimens for mesorectal bulk, surface regularity, defects, coning, and overall grade were 0.85, 0.85, 0.92, 0.84, and 0.91. When compared with all raters, pathologists and residents had higher agreement and pathologists and surgeons had lower agreement. Ordinal α-values comparing pathologist and pathologist's assistant agreement for overall grade were similar pre- and postfixation (0.78 vs 0.80), but agreement for assessing defects decreased postfixation. Among pathologists' assistants, agreement was higher when grading specimens postfixation than when grading fresh specimens. Assessment bias may have occurred because of the greater number of pathologists' assistants participating than the number of residents and pathologists. The results indicate good interrater agreement for the assessment of overall grade, with defects showing the best interrater agreement in fresh specimens. Although total mesorectal excision specimens may be consistently graded postfixation, the assessment of defects postfixation may be less reliable. This study highlights the need for additional knowledge-transfer activities to ensure consistency and accurate grading of total mesorectal excision specimens.

2012-01-01

Summary This is a study of 120 patients of either sex and all ages who had sustained deep burns of up to 40% of the total body surface area. Half the patients underwent early excision and skin autografting (i.e., within 4-7 days of sustaining burn injury) while the rest underwent delayed excision and skin autografting (i.e., within 1-4 weeks post-burn). Significant differences were found in favour of the early excision and grafting group with regard to the various burn management outcome parameters taken into consideration, i.e. culture positivity of wounds, graft take, duration of post-graft hospitalization, and mortality.

Anterior resection with total mesorectal excision is the standard method of rectal cancer resection. However, this procedure remains technically difficult in mid and low rectal cancer. A robotic transanal proctectomy with total mesorectal excision and laparoscopic assistance is reported in a 57 year old male with BMI 32 kg/m2 and rectal adenocarcinoma T2N1M0 at 5 cm from the dentate line. Operating time was 420 min. Postoperative hospital stay was 6 days and no complications were observed. Pathological report showed a 33 cm specimen with ypT2N0 adenocarcinoma at 2 cm from the distal margin, complete TME and non affected circumferential resection margin. Robotic technology might reduce some technical difficulties associated with TEM/TEO or SILS platforms in transanal total mesorectal excision. Further clinical trials will be necessary to assess this technique. Copyright © 2013 AEC. Published by Elsevier Espana. All rights reserved.

Early excision has considerably improved outcome in extensive burns, but massive resections usually mean copious bleeding that must be conveniently corrected. The purpose of this study was to measure blood component use during escharectomies in children. All pediatric patients with acute burns excised at the Burn Unit of the Hospital Garrahan during one year were included. Volume of blood component used during and immediately after surgery was analyzed and related to percent excised, time post-burn, and the coexistence of infection and autograft at the time of excision. Ninety-four surgeries in 51 children aged 0-14 years with total burned body surface areas of 5-80% who underwent resections of 3-70% were studied. Total blood use (intra + post-operatively) was 2.07 ml/kg/%excised for red blood cells (60% during surgery) and 0.7 ml/kg/% excised for plasma. Only 12% of patients required platelet transfusion. There was no significant requirement variation with the existence of infection, grafting or time post-burn. Approximately 2 ml/kg/% excised of red blood cells (2/3 for surgery) and 1 ml/kg/% excised of plasma are needed for escharectomies in children. The need for platelets must be judged considering the individual patient.

Microsurgical Resection of Suprasellar Craniopharyngioma-Technical Purview.

Objectives  Complete surgical resection is an important prognostic factor for recurrence and is the best management for craniopharyngioma. This operative video demonstrates the technical nuances in achieving complete resection of a suprasellar craniopharyngioma. Design and Setting  The surgery was performed in a middle-aged lady who presented with the history of progressive bitemporal hemianopia and excessive sleepiness over 8 months. On imaging, suprasellar craniopharyngioma was identified. The tumor was approached through opticocarotid cistern and lamina terminalis. Exposure of bilateral optic nerves, right internal carotid artery, anterior cerebral artery, and its perforator branches was then afforded and the tumor was gross totally resected. Results  The author demonstrates step-by-step technique of microsurgical resection of suprasellar craniopharyngioma. The narrow corridor to deeper structures, intricacies of multiple perforator vessels, and the technique of arachnoid and capsule dissection are the main challenging factors for the gross total resection of craniopharyngioma. The tumor portion which lies under the ipsilateral optic nerve is a blind spot region with a high chance of leaving residual tumor. Mobilization of optic nerve may endanger visual function too. The use of handheld mirror ['mirror-technique'] helps in better visualization of this blind spot and achieve complete excision. Conclusions  The technical pearls of craniopharyngioma surgery include the optimum utilization of translamina terminalis route, wide opening of the cisterns, meticulous separation of deep perforator vessels, capsular mobilization/traction avoidance, and the use of "mirror-technique" for blind-spot visualization. These surgical strategies help to achieve complete resection without causing neurological deficit. The link to the video can be found at: https://youtu.be/9wHJ4AUpG50 .

Branchial arch anomalies (BAA) represent one of the commonest pediatric neck masses, but large case series are lacking with none specifically examining risk of recurrence, surgical complications, and malignancy. Retrospective study of patients with BAA at Mayo Clinic from 1/1/1976-7/29/2011. Features studied include age, gender, location, BAA type, symptoms, recurrence, preoperative management, extent of surgery, pathology as well as presence of tracts. Associations with tracts, operative complications, and recurrence were evaluated. 421 subjects underwent BAA excision during the study period at our institution. Subjects with tracts were symptomatic earlier. Four cases (mean age 60.3 years) of malignancy were identified. Among the 358 (non-remenant) BAA patients with no previous excision, 3.6% recurred at a mean of 47.1 months following surgery. Patients who underwent incision and drainage prior to BAA excision were 3.4 times more likely to recur. 2% experienced complications. Age, BAA type, preoperative imaging and extent of surgery did not affect recurrence or complication rates. Patients with history of preoperative incision and drainage should be followed closely for recurrence the first four years. Early BAA excision is not associated with higher complication rate. Extent of resection should be determined by gross margins of BAA. Malignant degeneration was not seen in children. Malignancies have been seen in older patients (over 45 years) diagnosed with BAA, and a thorough work-up is important for correct diagnosis. Copyright © 2017 Elsevier B.V. All rights reserved.

Management of intraductal papilloma without atypia of the breast diagnosed on core biopsy: Size and sampling matter.

PubMed

Symbol, Brittany; Ricci, Andrew

2018-04-23

Due to the potential for atypia (atypical ductal or lobular hyperplasia) or carcinoma (in situ or invasive) on excision, aggressive reflex surgical excision protocols following core biopsy diagnosis of papillary lesions of the breast (ie, intraductal papilloma) are commonplace. Concepts in risk stratification, including radiologic-pathologic correlation, are emerging in an effort to curb unnecessary surgeries. To this end, we examined all excised intraductal papillomas diagnosed at our institution from 2010-2015 (N = 336) and found an overall atypia rate of 20%. To investigate further, we stratified all excised papillomas according to total lesion size (range = 1-40 mm) and found that the atypia rate for lesions ≤1.2 cm (16% with atypia) was statistically significantly lower (P = .008) than the atypia rate for lesions >1.2 cm (36% with atypia). To explore to effects of radiologic-pathologic correlation on the ability of the core biopsy to accurately predict nonatypical lesions we assessed thirteen consecutive paired nonatypical core biopsy/follow-up surgical excision specimens for the percent of the total lesion (on imaging) sampled by the core biopsy (measured histologically). None of the thirteen paired specimens showed upgrade on excision (0/13); the percent of total lesion sampled by biopsy in this cohort averaged 59%. We propose that in the absence of discordant clinical/radiological findings, small lesions (≤1.2 cm) with radiologic-pathologic concordance (>50% sampling of total lesion by core biopsy) may safely forego surgery for close clinical and radiographic follow-up. © 2018 Wiley Periodicals, Inc.

2018-03-01

Scapulectomy is an inevitable treatment for sarcomas of the scapula. This procedure is unavoidable because it reduces the local recurrence rate but can impair shoulder movements and affect the activities of daily living. This study investigated the factors influencing functional outcomes after scapulectomy. The clinical results of 8 patients (5 males, 3 females) who were diagnosed with primary or metastatic sarcomas of the scapula were retrospectively reviewed. The mean age was 49 years (range, 11-86 years). We examined the correlation between the type of excision of the scapula (total, subtotal, or partial) and postoperative functional outcomes according to the Musculoskeletal Tumor Society (MSTS) score. In partial excision, the glenohumeral joint was preserved; in subtotal excision, the glenoid was completely resected and some bony components were preserved; and in total excision, the entire bony component of the scapula was resected. The average follow-up period was 55 months (range, 9-142 months). The partial, subtotal, and total excision groups had mean functional scores of 96.7%, 76.7%, and 62.2%, respectively. Although the mean functional scores were lower in patients who underwent total and subtotal excisions, 3 patients in whom the latissimus dorsi muscle was preserved had better function (mean MSTS score, 76.7%) than the 2 patients in whom it was not preserved (mean MSTS score, 55.0%). These results suggest that the latissimus dorsi muscle, along with the deltoid and pectoralis major muscles, is one of the stabilizers of the proximal humerus after scapulectomy.

Ritter, M. A.; Davis, K. E.; Meding, J. B.; Farris, A.

2012-01-01

Objectives The purpose of this study was to examine the effect of posterior cruciate ligament (PCL) retention, PCL recession, and PCL excision during cruciate-retaining total knee replacement. Methods A total of 3018 anatomic graduated component total knee replacements were examined; 1846 of these retained the PCL, 455 PCLs were partially recessed, and in 717 the PCL was completely excised from the back of the tibia. Results Clinical scores between PCL groups favored excision for flexion (p < 0.0001), and recession and retention for stairs (p < 0.0001). There was a mild difference in long-term all-cause aseptic survivorship between PCL-retained (96.4% at 15 years) combined with PCL-recessed groups (96.6% at 15 years) when compared with the PCL-excised group (95.0% at 15 years) (p = 0.0411, Wilcoxon; p = 0.0042, log-rank), as well as tibial or femoral loosening, which reported prosthesis survival of 97.8% at 15 years for PCL-retained knees, 98.2% for recessed knees, and 96.4% for excised knees (p = 0.0934, Wilcoxon; p = 0.0202, log-rank). Conclusions Despite some trade off in clinical performance, if the PCL is detached at the time of operation, conversion to a posterior-stabilised prosthesis may not be necessarily required as long as stability in the anteroposterior and coronal planes is achieved.

Craniopharyngioma

Garnett, Matthew R; Puget, Stéphanie; Grill, Jacques; Sainte-Rose, Christian

2007-01-01

Craniopharyngiomas are benign slow growing tumours that are located within the sellar and para sellar region of the central nervous system. The point prevalence of this tumour is approximately 2/100,000. The onset of symptoms is normally insidious with most patients at diagnosis having neurological (headaches, visual disturbances) and endocrine (growth retardation, delayed puberty) dysfunctions. Craniopharyngiomas are thought to arise from epithelial remnants of the craniopharyngeal duct or Rathke's pouch (adamantinomatous type) or from metaplasia of squamous epithelial cell rests that are remnants of the part of the stomadeum that contributed to the buccal mucosa (squamous papillary type). The neuroradiological diagnosis is mainly based on the three components of the tumour (cystic, solid and calcified) in the characteristic sellar/para sellar location. Definitive diagnosis is made following histological examination of a surgical specimen. The differential diagnosis includes other tumours in this region (pituitary adenoma), infectious or inflammatory processes (eosinophilic granuloma), vascular malformations (aneurysm) and congenital anomalies (Rathke's cleft cyst). The current treatment is gross total excision of the tumour, if there is no hypothalamic invasion or, in the presence of hypothalamic invasion, a sub-total resection with post-operative radiotherapy. Endocrine disturbances are normally permanent and need careful replacement. Overall, there is an 80% 5 year survival, though this can be associated with marked morbidity (hypothalamic dysfunction, altered neuropsychological profile). PMID:17425791

Lymphangiectasia of small intestine presenting as intussusception.

Katoch, Pervez; Bhardwaj, Subhash

2008-01-01

Intussusception is defined as telescoping of a segment of gastrointestinal tract into an adjacent one. In small children, it is the commonest cause of intestinal obstruction. More than 90% of childhood intussusceptions are idiopathic. We report a rare case of localized small intestinal lymphangiectasia, presenting as intussusception in a 6-month-old male child. The child presented with features of acute intestinal obstruction for which he was later operated. The gross examination of excised ileocecal mass revealed intussusception. Histopathologic examination revealed lymphangiectasia of small intestine, which acted as a lead point for ileocecal intussusception. Postoperative period was uneventful.

Calli were induced either from excised rice embryos or from whole seeds in the presence of 1 to 5 mg l-1 NAA. After 12 days of culture, calli were induced only from excised rice embryos. We found that excised embryos accumulated NAA up to 6 times higher concentration than did whole seeds. In the presence of 1 to 5 mg l-1 NAA and 2 to 10 mg l-1 kinetin, chlorophyllous calli were induced from excised rice embryos. Chlorophyll contents in the callus tissue increased with increasing kinetin concentration while percent callus induction decreased. The total chlorophyll content was linearly correlated with the ratio of kinetin to NAA in the medium.

Background Skin cancers are the most common malignancy in New Zealand and their treatment imparts a huge burden on the healthcare system both in terms of the cost of surgical intervention and in treatment delivery (estimates are in excess of NZ$33 million per annum for the year 2000). Currently in New Zealand, skin cancers are excised by dermatologists, general practitioners (GPs), GPs with a special interest in skin surgery (GPSIs) and specialist surgeons with diverse training backgrounds including ear, nose and throat, ophthalmic and general surgeons. To date there is scant literature evaluating complete excision rates following surgical treatment of skin cancer between these vocational groups. Objectives To review retrospectively pathology reports from all skin excisions sent to one private pathology laboratory over three consecutive months. The aim was to investigate the margins of excision and completeness of skin cancer surgery performed by each vocational group. Methods A retrospective analysis of skin pathology reports was undertaken for a 3-month period between April and June 2007. Raw data obtained from the pathology reports included diagnosis, completeness of excision, size of specimens, body site and vocational group of the medical practitioner performing the surgery. Results In total, 1532 lesions were excised: 432 benign and 1100 malignant. Six hundred and seven were from the head and neck. Dermatologists excised 276 lesions of which 93% were malignant, 55% were from the head and neck, and 0% were incompletely excised. GPs excised 633 lesions: 63% malignant, 30% head and neck, 23% incomplete excision of malignant lesions. GPSIs excised 368 lesions: 71% malignant, 35% head and neck, 21.5% incomplete malignant excision. Specialist surgeons excised 255 lesions: 72% malignant, 53% head and neck, 20% incomplete malignant excision. Conclusion GPs and GPSIs excised more benign lesions and had higher incomplete excision rates of skin cancer surgery than dermatologists. Incomplete excision rates for the vocational groups ranged from 0% to 45% depending on site and pathology.

Intracranial germ cell tumors (IGCTs) are a group of rare pediatric brain tumors which include various subtypes. The current understanding of the etiology of the tumors and their optimal management strategies remain controversial. The data on IGCTs were collected from articles published in the past 20 years, and the origin and etiology of IGCTs at molecular level as well as the relative roles of varied treatment strategies in different prognosis groups according to Matsutani's classification were reviewed. Recent cellular and molecular evidence suggests that IGCTs may arise from the transformation of endogenous brain cells; and findings in the molecular characterization of IGCTs suggest roles of CCND2, RB1, and PRDM14 in the pathogenesis of IGCTs and identify the KIT/RAS and AKT1/mTOR pathways as potential therapeutic targets in future. According to Matsutani's classification of IGCTs, the good prognosis group includes both germinomas and mature teratomas. For germinomas, both radiation alone and reduced-dose radiotherapy in combination with adjuvant chemotherapy are effective, while complete surgical excision is recommended for mature teratomas. In the intermediate prognosis group, immature teratoma has been successfully treated with gamma knife surgery. However, for intermediate prognosis IGCTs other than immature teratomas, gross total resection with adjuvant chemotherapy and radiotherapy or gamma knife surgery may be necessary to achieve cure. In the poor prognosis group, survival outcomes are unsatisfactory, and complete surgical resection combined with more intensive chemotherapy and radiotherapy remains the best available treatment option at this time. IGCTs should be strictly classified according to their pathological categories before administering pathology-specific treatments. Although open microsurgical excision is the traditional surgical strategy for IGCTs, recent publications also support the role of endoscopic surgical options for pineal region IGCTs.

A primary intraosseous hemangioma (IOH) of the orbital bone is extremely rare. The preferred method of treatment for IOH is total surgical excision with reconstruction. Herein, the authors describe a patient with an orbital roof IOH and the unexpected complications of ptosis and deteriorated exophthalmos. These findings showed that the total surgical excision and subsequent reconstruction provided adequate decompression and prevented further ocular complications from the orbital wall defect.

Evaluation of the entire surgical margin results in high rates of complete excision, low local recurrence rates, and maximal tissue conservation. Although well recognized for melanoma of the head and neck, few studies have focused exclusively on the trunk and proximal extremities. We sought to evaluate the efficacy of Mohs micrographic surgery for melanoma in situ (MIS) of the trunk and proximal extremities, and determine adequate excision margins for MIS when total margin evaluation is not used. Long-term outcomes in 882 cases of MIS treated with Mohs micrographic surgery were analyzed and compared with historical controls. Rates of complete excision were determined for increasing surgical margin intervals. One local recurrence occurred in our cohort (0.1%). Only 83% of MIS were excised with a 6-mm margin. Margins of 9 mm were needed to excise 97% of MIS, statistically equivalent to thin melanomas. We used a nonrandomized, single-institution, retrospective design. Mohs micrographic surgery may cure the 17% of MIS that exceed traditional excision margins of 5 mm and is a valuable option for these patients. Surgical margins of at least 0.9 cm should be considered for MIS of the trunk and extremities when total margin evaluation is not used. Copyright © 2016 American Academy of Dermatology, Inc.

2016-01-01

The concept of complete mesocolic excision and central vascular ligation for colonic cancer has been recently introduced. The paper describes a technique of right-sided complete mesocolic excision and intracorporeal anastomosis by using a single-port robotic approach with an additional conventional robotic port. We performed a single-port plus an additional port robotic surgery using the Da Vinci Single-Site platform via the Pfannenstiel incision and the wristed robotic instruments via an additional robotic port in the left lower quadrant. The total operative and docking times were 280 and 25 minutes, respectively. The total number of lymph nodes harvested was 36 and the proximal and distal resection margins were 31 and 50 cm, respectively. Single-port plus an additional port robotic surgery for right-sided complete mesocolic excision and intracorporeal anastomosis appears to be feasible and safe. This system can overcome certain limitations of the previous robotic systems and conventional single-port laparoscopic surgery. PMID:27757400

Silver, A G; Zamboni, W A; Baynosa, R C

Acute burns suffered from contact with environmentally heated roadways and walkways are a rare entity. The aim of this report is to assess the information gained from the treatment of a series of patients. A retrospective review of a consecutive series of cases, where operative treatment was necessary, that occurred during July 2010 in southern Arizona. Seven patients were included, with an average total body surface area burn of 10.2%. Direct fascial excision and tangential excision were carried out on three and four patients, respectively. Although tangential excision was carried out to normal endpoints, there was commonly a need for repetitive debridement. The total hospital costs were over $4,400,000 (£2,730,000). Burns suffered from contact with roadways/walkways are often deeper than suggested by their appearance. Direct fascial excision minimises the number of debridement sessions. We hypothesise that the failure to offload pressure on these wounds may be a causative factor in their observed deepening.

Artificial excision of the distal part of acorns in order to promote germination is well researched in oak seedling cultivation studies. However, studies of combined effects of cotyledon excision and nursery fertilization on container seedlings are lacking, especially for seedling root growth and outplanting performance. This study aimed to explore the main effects of cotyledon excision on Quercus variabilis seedling emergence characteristics and demonstrated the combined effects of cotyledon excision and nursery fertilization on seedling quality to improve Quercus variabilis seedling outplanting performance. Four cotyledon excision treatments and two classes of nursery fertilization were implemented. Seedling emergence was noted every week after sowing. Seedling dry mass, morphology, and nutrient status were assessed at the end of the nursery season. After the first outplanting season, the aforementioned measurements along with seedling survival were determined once again. The results showed that cotyledon excision generally induced greater and more rapid seedling emergence, but did not affect shoot emergence synchronicity. The highest total emergence and emergence rate occurred with Intermediate excision (1/2 of the distal end of acorn was excised). Effects of nutrient loss due to cotyledon excision on seedling quality and outplanting performance were somewhat compensated by nursery fertilization. Nursery fertilization promoted dry mass increment (the net increment from T0 to T2 for dry mass) for excised seedlings after outplanting, resulting in better performance for Slight (1/3 of the distal end of acorn was excised) and Intermediate excision treatments in the field. Thus we conclude Intermediate excision combined with reasonable nursery fertilization can be recommended for production of nursery grown seedlings for afforestation. PMID:28545103

The major problem in the treatment of rectal cancer is local recurrence. After the introduction of total mesorectal excision (TME), the recurrent rate decreased from 100% to around 10%. The purpose of the present study was to evaluate the quality of organ and tissue plane preservation in soft cadaver and to assess the feasibility to perform the procedure (mobilization of colon and rectum, total mesorectal excision and stapler anastomosis) in soft cadaver. Colorectal Division, Department of Surgery and Surgical Training Center Department of Anatomy, Faculty of Medicine, Chulalongkorn University. Prospective descriptive study. Seven soft cadavers were used for total mesorectal excision (TME) training. These procedures were performed by 21 participants (1 soft cadaver for 3 participants). The procedures were done under the supervision of experienced colorectal surgeons. The successfulness, satisfaction in performing the procedure and the quality of organ preservation were evaluated using standardized questionnaires. Participants were satisfied about TME training in soft cadaver (mean 8.24-8.71) and rated that soft cadavers were good in terms of internal organs and tissue plane preservation (mean 7.19-8.19) (0 = extremely unsatisfied, 10 = extremely satisfied). Training of TME in soft cadaver is feasible. The similarity in tissue quality (texture, consistency, color) of the preserved organs to that of the living and the good feel of performing the procedure make the trainee better understand the techniques and improve their skills.

Total proctocolectomy with ileal pouch-anal anastomosis (TPCIAA) is the procedure of choice for patients with Ulcerative Colitis and Familial Adenomatous Polyposis. The frequency of presentation of both diseases is low in Mexico, therefore the experience with the surgical procedure is limited. To analyze the operative morbidity and mortality and long-term functional results in a series of patients operated upon with the TPCIAA in a referral center in Mexico. Retrospective analysis of 44 consecutive patients operated upon from 1987 through 1997. The operation included resection of the anal transitional zone, handsewn anastomosis of a "J" pouch, and diverting ileostomy in all cases. Operative morbidity and mortality, and long-term functional results and complications were determined. Mean age was 33 +/- 15 years. There were 52% women and 48% men. Diagnoses were ulcerative colitis in 59% and familial polyposis in 36%. Global morbidity was 39%, and mortality 2%. With a mean follow-up of 24 months, mean number of bowel movements was 4, 10% of patients had diurnal spotting, 30% nocturnal spotting, and no patient had gross incontinence. Three patients presented pouchitis with adequate response to antibiotics. Two patients presented long-term pouch fistulas that did not require pouch excision. The TPCIAA is a feasible operation with acceptable rates of morbidity and mortality and satisfactory functional results.

The Gross Morphology and Histochemistry of Respiratory Muscles in Bottlenose Dolphins, Tursiops truncatus

Most mammals possess stamina because their locomotor and respiratory (i.e., ventilatory) systems are mechanically coupled. These systems are decoupled, however, in bottlenose dolphins (Tursiops truncatus) as they swim on a breath-hold. Locomotion and ventilation are coupled only during their brief surfacing event, when they respire explosively (up to 90% of total lung volume in approximately 0.3s) (Ridgway et al., 1969). The predominantly slow-twitch fiber profile of their diaphragm (Dearolf, 2003) suggests that this muscle does not likely power their rapid ventilatory event. Based upon Bramble's (1989) biomechanical model of locomotor-respiratory coupling in galloping mammals, it was hypothesized that locomotor muscles function to power ventilation in bottlenose dolphins. It was further hypothesized that these muscles would be composed predominantly of fast-twitch fibers to facilitate the bottlenose dolphin's rapid ventilation. The gross morphology of cranio-cervical (scalenus, sternocephalicus, sternohyoid), thoracic (intercostals, transverse thoracis), and lumbo-pelvic (hypaxialis, rectus abdominis, abdominal obliques) muscles (n=7) and the fiber-type profiles (n=6) of selected muscles (scalenus, sternocephalicus, sternohyoid, rectus abdominis) of bottlenose dolphins were investigated. Physical manipulations of excised thoracic units were carried out to investigate potential actions of these muscles. Results suggest that the cranio-cervical muscles act to draw the sternum and associated ribs cranio-dorsally, which flares the ribs laterally, and increases the thoracic cavity volume required for inspiration. The lumbo-pelvic muscles act to draw the sternum and caudal ribs caudally, which decreases the volumes of the thoracic and abdominal cavities required for expiration. All muscles investigated were composed predominantly of fast-twitch fibers (range 61-88% by area) and appear histochemically poised for rapid contraction. These combined results suggest that dolphins utilize muscles, similar to those used by galloping mammals, to power their explosive ventilation. PMID:18777569

Awake Craniotomy with Noninvasive Brain Mapping by 3-Tesla Functional Magnetic Resonance Imaging for Excision of Low-grade Glioma: A Case of a Young Patient from Pakistan.

PubMed

Aleem Bhatti, Atta Ul; Jakhrani, Nasir Khan; Parekh, Maria Adnan

2018-01-01

The past few years have seen increasing support for gross total resection in the management of low-grade gliomas (LGGs), with a greater extent of resection correlated with better overall survival, progression-free survival, and time to malignant transformation. There is consistent evidence in literature supporting extent of safe resection as a good prognostic indicator as well as positively affecting seizure control, symptomatic relief in pressure symptoms, and longer progression-free and total survival. The operative goal in most LGG cases is to maximize the extent of resection for these benefits while avoiding postoperative neurologic deficits. Several advanced invasive and noninvasive surgical techniques such as intraoperative magnetic resonance imaging (MRI), fluorescence-guided surgery, intraoperative functional pathway mapping, and neuronavigation have been developed in an attempt to better achieve maximal safe resection. We present a case of LGG in a young patient with a 5-year history of refractory seizures and gradual onset walking difficulty. Serial MRI brain scans revealed a progressive increase in right frontal tumor size with substantial edema and parafalcine herniation. Noninvasive brain mapping by functional MRI (fMRI) and sleep-awake-sleep type of anesthesia with endotracheal tube insertion was utilized during an awake craniotomy. Histopathology confirmed a Grade II oligodendroglioma, and genetic analysis revealed no codeletion at 1p/19q. Neurological improvement was remarkable in terms of immediate motor improvement, and the patient remained completely seizure free on a single antiepileptic drug. There is no radiologic or clinical evidence of recurrence 6 months postoperatively. This is the first published report of an awake craniotomy for LGG in Pakistan. The contemporary concept of supratotal resection in LGGs advocates generous functional resection even beyond MRI findings rather than mere excision of oncological boundaries. This relatively aggressive approach is only possible with an awake craniotomy, which ensures preservation of functional status and thus less postoperative morbidity and better outcomes. Noninvasive mapping for intracranial space-occupying lesions, including fMRI and blood-oxygen-level dependent (BOLD) imaging modality, is an essential tool in a resource-limited setting such as Pakistan.

Neurofibromatosis may present with different skin lesions. Disfiguring lesions on the face might be challenging for the surgeon or clinician to correct and may have adverse effects on patients' social lives, especially in young women. To present the dermabrasion technique combined with serial excisions of a deeper accompanying lesion to treat superficial facial lesions in a young neurofibromatosis patient. Dermabrasion was applied to superficial lesions on the face, and staged excision was applied to the deeper lesion located on the forehead. We obtained high patient satisfaction with the result. The deep lesion was excised totally, and superficial lesions were decreased with dermabrasion. Dermabrasion may become a good alternative in cases of neurofibromatosis with superficial facial lesions.

A 29-year-old patient had undergone an elective lower-segment caesarean section (LSCS) five months previously at a district hospital. The operation and the immediate postoperative period were uneventful. After five months she presented back with a fistulous opening. A fistulogram revealed a connection between the uterus and the skin. Fistulous tract excision was planned. Intraoperatively there was communication between the skin and the uterine cavity, with extensive necrosis of the uterine wall. The patient gave her informed consent for excision of the fistulous tract and/or total abdominal hysterectomy. During surgery, it was deemed that there was no scope for excision, so the decision was made for a total abdominal hysterectomy. Histopathological examination confirmed tuberculosis and the patient responded well to anti-tubercular drugs. This case report describes a rare presentation of tubercular uterocutaneous fistula after caesarean section.

Although survival outcomes have been evaluated between those undergoing a planned primary excision and those undergoing a reexcision following an unplanned resection, the financial implications associated with a reexcision have yet to be elucidated. A query for financial data (professional, technical, indirect charges) for soft tissue sarcoma excisions from 2005 to 2008 was performed. A total of 304 patients (200 primary excisions and 104 reexcisions) were identified. Wilcoxon rank sum tests and χ2 or Fisher's exact tests were used to compare differences in demographics and tumor characteristics. Multivariable linear regression analyses were performed with bootstrapping techniques. The average professional charge for a primary excision was $9,694 and $12,896 for a reexcision (p<.001). After adjusting for tumor size, American Society of Anesthesiologists status, grade, and site, patients undergoing reexcision saw an increase of $3,699 in professional charges more than those with a primary excision (p<.001). Although every 1-cm increase in size of the tumor results in an increase of $148 for a primary excision (p=.006), size was not an independent factor in affecting reexcision charges. The grade of the tumor was positively associated with professional charges of both groups such that higher-grade tumors resulted in higher charges compared to lower-grade tumors (p<.05). Reexcision of an incompletely excised sarcoma results in significantly higher professional charges when compared to a single, planned complete excision. Additionally, when the cost of the primary unplanned surgery is considered, the financial burden nearly doubles.

Managing Recurrence in Intraarticular Melorheostosis Involving the Knee Joint: A Case Report.

PubMed

John, Bobby; Sharma, Anirudh; Pandey, Ritesh A

2017-01-01

Melorheostosis is a rare benign sclerosing dysplasia affecting bone, which causes significant morbidity in the form of pain and restriction of joint movement. Treatment options are varied, and recurrence is common after surgical treatment. Choosing the most appropriate treatment option in the management of a recurrent case is challenging, with very little supporting evidence in literature owing to the rarity of the disease. We hereby present a case of recurrent melorheostosis involving the knee; discuss treatment options and the rationale of our treatment. We present the case of a 42-year-old female who was operated at our institution previously 7 years ago for melorheostosis of her left knee and had undergone excision of intrarticular hyperostotic masses. However, pain and limitation of motion recurred in the operated knee 4 years later, and radiographs and computed tomography revealed a mineralized mass situated behind the patella in the patellofemoral joint. She was treated with repeat open excision of the mass and put on a regimen of physiotherapy and bisphosphonates. Open excision of symptomatic hyperostotic or mineralized soft tissue masses is perhaps the favored treatment option in such cases, the other options being arthroscopic excision and total knee arthroplasty. Limited knee motion and size of the mass often make arthroscopy an unfeasible option. Total knee arthroplasty should be reserved for cases with significant flexion contractures of the knee, or where multiple excisions have failed.

Gross Motor Skills and Cardiometabolic Risk in Children: A Mediation Analysis.

2017-04-01

The purpose of this study was to examine the linear relationship between gross motor skills and cardiometabolic risk, with aerobic fitness as a mediator variable, in low-income children from the United States. Participants were a convenience sample of 224 children (mean ± SD age = 9.1 ± 1.1 yr; 129 girls and 95 boys) recruited from five low-income elementary schools from the Mountain West Region of the United States. Gross motor skills were assessed using the Test for Gross Motor Development, 3rd Edition. Gross motor skills were analyzed using a locomotor skill, a ball skill, and a total gross motor skill score. Aerobic fitness was assessed using the Progressive Aerobic Cardiovascular Endurance Run that was administered during physical education class. A continuous and age- and sex-adjusted metabolic syndrome score (MetS) was calculated from health and blood marker measurements collected in a fasted state before school hours. Total effects, average direct effects, and indirect effects (average causal mediation effect) were calculated using a bootstrap mediation analysis method via a linear regression algorithm. The average causal mediation effect of gross locomotor skills on MetS scores, using aerobic fitness as the mediator variable, was statistically significant (β = -0.055, 95% confidence interval = -0.097 to -0.021, P = 0.003). The model explained approximately 17.5% of the total variance in MetS with approximately 43.7% of the relationship between locomotor skills and MetS mediated through aerobic fitness. Ball skills did not significantly relate with cardiometabolic risk. There is a significant relationship between gross locomotor skills and cardiometabolic risk that is partially mediated through aerobic fitness in a sample of low-income children from the United States.

To assess the efficacy of a modified approach with transanal total mesorectal excision (taTME) using simple customized instruments in male patients with low rectal cancer. A total of 115 male patients with low rectal cancer from December 2006 to August 2015 were retrospectively studied. All patients had a bulky tumor (tumor diameter ≥ 40 mm). Forty-one patients (group A) underwent a classical approach of transabdominal total mesorectal excision (TME) and transanal intersphincteric resection (ISR), and the other 74 patients (group B) underwent a modified approach with transabdominal TME, transanal ISR, and taTME. Some simple instruments including modified retractors and an anal dilator with a papilionaceous fixture were used to perform taTME. The operative time, quality of mesorectal excision, circumferential resection margin, local recurrence, and postoperative survival were evaluated. All 115 patients had successful sphincter preservation. The operative time in group B (240 min, range: 160-330 min) was significantly shorter than that in group A (280 min, range: 200-360 min; P = 0.000). Compared with group A, more complete distal mesorectum and total mesorectum were achieved in group B (100% vs 75.6%, P = 0.000; 90.5% vs 70.7%, P = 0.008, respectively). After 46.1 ± 25.6 mo follow-up, group B had a lower local recurrence rate and higher disease-free survival rate compared with group A, but these differences were not statistically significant (5.4% vs 14.6%, P = 0.093; 79.5% vs 65.1%, P = 0.130). Retrograde taTME with simple customized instruments can achieve high-quality TME, and it might be an effective and economical alternative for male patients with bulky tumors.

Forty-one patients (group A) underwent a classical approach of transabdominal total mesorectal excision (TME) and transanal intersphincteric resection (ISR), and the other 74 patients (group B) underwent a modified approach with transabdominal TME, transanal ISR, and taTME. Some simple instruments including modified retractors and an anal dilator with a papilionaceous fixture were used to perform taTME. The operative time, quality of mesorectal excision, circumferential resection margin, local recurrence, and postoperative survival were evaluated. RESULTS All 115 patients had successful sphincter preservation. The operative time in group B (240 min, range: 160-330 min) was significantly shorter than that in group A (280 min, range: 200-360 min; P = 0.000). Compared with group A, more complete distal mesorectum and total mesorectum were achieved in group B (100% vs 75.6%, P = 0.000; 90.5% vs 70.7%, P = 0.008, respectively). After 46.1 ± 25.6 mo follow-up, group B had a lower local recurrence rate and higher disease-free survival rate compared with group A, but these differences were not statistically significant (5.4% vs 14.6%, P = 0.093; 79.5% vs 65.1%, P = 0.130). CONCLUSION Retrograde taTME with simple customized instruments can achieve high-quality TME, and it might be an effective and economical alternative for male patients with bulky tumors.

During surgery for choledochal cyst (CC), any intrapancreatic CC (IPCC) must also be excised to prevent postoperative pancreatitis and stone formation. We report our technique for laparoscopic total IPCC excision (n = 16; mean age 6.0 years). We insert a fine ureteroscope with a light source into the opened CC through an extra 3.9-mm trocar placed in the epigastrium through a minute incision to identify the pancreatic duct orifice. By pulling the end of the ureteroscope emerging from the trocar gently to withdraw the tip from the pancreatic duct to where distal dissection was ceased under laparoscopic view, the IPCC can be measured. If longer than 5 mm, the distal CC is dissected further caudally until it is less than 5 mm. For accuracy, the distal CC is elevated with a suture that is exteriorized and clamped to provide constant traction. The IPCC was able to be measured in 11/16 (68 %). Initial lengths measured were 3-10 mm (5.2 ± 2.7 mm). Final IPCC were all 5 mm or less. Surgery was uncomplicated without any pancreatic duct injury and postoperative recovery was unremarkable. Follow-up MRI at 32 months showed no IPCC in any case. Measuring the IPCC enables total CC excision, thus reducing the potential for postoperative complications.

Intraductal papilloma (IDP) is well-known as one of the common benign breast lesions requiring excision. However, treatment of IDP without atypia is controversial. The aim of our study was to determine the proper management of solitary IDP by core needle biopsy (CNB). We retrospectively reviewed patients with solitary IDP confirmed by CNB from March 2003 to March 2015. We collected data about final pathology after excision, as well as clinical, histologic, and radiologic findings at initial diagnosis. The final pathology was categorized as benign or malignant. We evaluated the rate of upgrade to malignancy and factors associated with malignancy. We identified 405 patients who presented benign solitary IDP by CNB. The mean age was 46.1 years (range, 15-86 years). In total, 135 patients underwent surgical excision, and 211 underwent vacuum-assisted excision. Of 346 patients, malignant lesions were found in 8 patients (2.3%): 7 underwent surgical excision, and 1 underwent vacuum-assisted excision. Only the size of IDP was significantly associated with cancer upgrade (P = .003). Our study shows that overall malignancy upgrade rate of benign solitary IDP after excision is very low (2.3%). Even when the size of IDP was less than 1 cm, the upgrade rate to cancer was only 0.9%. Therefore, for patients with small solitary IDP, we recommend close follow-up with ultrasound instead of excision. Copyright © 2017 Elsevier Inc. All rights reserved.

The aim of this study is to assess the indirect costs of six major autoimmune diseases including seropositive rheumatoid arthritis, other types of rheumatoid arthritis, psoriasis, multiple sclerosis, Type 1 diabetes, and ulcerative colitis. Relevant data for 2012 on sick leave and short- and long-term work disabilities were obtained from the Social Insurance Institution in Poland. Indirect costs were estimated using the human capital approach based on gross domestic product per capita, gross value added per worker, and gross income per worker in Poland in 2012 and expressed in euro. We recorded data on the total number of 45,500 patients. The total indirect costs were EUR 146,862,569; 353,683,508; and 108,154,271, calculated using gross domestic product, gross value added, and gross income, respectively. Considering only data on absenteeism collected by the Social Insurance Institution in Poland, we can conclude that the selected autoimmune diseases are associated with great indirect costs.

This study is a comparison between three methods that are frequently used for the surgical treatment of pilonidal disease all over the world: modified excision and repair, wide excision and secondary repair, and wide excision and flap. The first technique is done by our group for the first time, and has not been described previously in the literature. This is an interventional study performed at Omid, Sadr, and Rasoul Akram hospitals on patients who had undergone operation because of pilonidal sinus disease and met the inclusion criteria between 2004 and 2007. Exclusion criteria were (1) acute pilonidal sinus diseases, (2) history of pilonidal sinus surgery, (3) history of systemic diseases (DM, malignancy, etc.), and (4) pilonidal abscess. Essential information was extracted from complete medical archives. Any data not available in files or during follow-up visits (all patients supposed to be followed at least for 1 year) were gathered by a telephone interview. A total of 194 patients met the criteria and had complete archived files. Longer duration of hospital stay was found in the "wide excision and closing with flap" method comparing with two other methods (P < 0.05). Length of incapacity for work was not different between the "wide excision and modified repair" and "wide excision" (P > 0.5) methods, but longer for "wide excision and flap" in comparison with two others (P < 0.05). Healing time was significantly longer in the "wide excision" method in comparison with two other methods (P < 0.05). However, "wide excision and modified repair" method had the least healing time between all above techniques, except for length of leaving the office. All the three recurrences (1.5 %) occurred in the wide excision and flap method (P < 0.05). The frequency of postoperative complications was 2 (3.3 %) in wide excision and modified repair, 15 (18.5 %) in wide excision, and 17 (32.7 %) in wide excision and flap closure; these differences in complications were statistically significant (P < 0.05). Our results show that the wide excision and modified repair technique, which has been described for the first time, is an acceptable method due to a low recurrence rate and better wound outcomes comparing with wide excision alone and wide excision and flap techniques for the surgical treatment of pilonidal sinus disease.

Next to surgical margins, yield of lymph nodes, and length of bowel resected, macroscopic completeness of mesorectal excision may serve as another quality control of total mesorectal excision (TME). In this study, the macroscopic completeness of laparoscopic TME was evaluated. A series of 25 patients with rectal cancer were managed laparoscopically (LTME) and included in this study. The pathologic specimens of the LTME group were prospectively examined and matched with a historical group of resection specimens from patients who had undergone open TME (OTME). The two groups were matched for gender and type of resection (low anterior or abdominoperineal resection). Special care was given to the macroscopic judgment concerning the completeness of the mesorectum. A three-grade scoring system showed no differences between the LTME and OTME groups. The current study supports the hypothesis that oncologic resection using laparoscopic TME is feasible and adequate.

GATA transcription factors and their Friend of Gata (FOG) cofactors control the development of diverse tissues. GATA4 and GATA6 are essential for the expansion of the embryonic liver bud, but their expression patterns and functions in the adult liver are unclear. We characterized the expression of GATA and FOG factors in whole mouse liver and purified hepatocytes. GATA4, GATA6, and FOG1 are the most prominently expressed family members in whole liver and hepatocytes. GATA4 chromatin immunoprecipitation followed by high throughput sequencing (ChIP-seq) identified 4409 occupied sites, associated with genes enriched in ontologies related to liver function, including lipid and glucose metabolism. However, hepatocyte-specific excision of Gata4 had little impact on gross liver architecture and function, even under conditions of regenerative stress, and, despite the large number of GATA4 occupied genes, resulted in relatively few changes in gene expression. To address possible redundancy between GATA4 and GATA6, both factors were conditionally excised. Surprisingly, combined Gata4,6 loss did not exacerbate the phenotype resulting from Gata4 loss alone. This points to the presence of an unusually robust transcriptional network in adult hepatocytes that ensures the maintenance of liver function. PMID:24367609

Physical activity can be promoted by high levels of gross motor skills. A systematic review found a positive relationship in children (3-18 years) but only few studies examined this in younger children. The aim of this study was to examine the association between gross motor skills and physical activity in children aged 11-29 months. Cross-sectional study. This study involved 284 children from 30 childcare services in NSW, Australia (Mean age=19.77±4.18months, 53.2% boys). Physical activity was measured using accelerometers (Actigraph GT3X+). Gross motor skills were assessed using the Peabody Developmental Motor Scales Second Edition (PDMS-2). Multilevel linear regression analyses were computed to assess associations between gross motor skills and physical activity, adjusting for sex, age and BMI. Children spent 53.08% of their time in physical activity and 10.39% in moderate to vigorous physical activity (MVPA). Boys had higher total physical activity (p<0.01) and MVPA (p<0.01) than girls. The average gross motor skills score was 96.16. Boys scored higher than girls in object manipulation (p<0.001). There was no association between gross motor skills and total physical activity or MVPA. Although gross motor skills were not associated with physical activity in this sample, stronger associations are apparent in older children. This study therefore highlights a potential important age to promote gross motor skills. Copyright © 2017 Sports Medicine Australia. Published by Elsevier Ltd. All rights reserved.

Musculus uvulae and velopharyngeal status.

Ijaduola, G T; Williams, O O

1987-06-01

A study of velopharyngeal status after partial excision of musculus uvulae, as in total uvulectomy, has been carried out in 15 adults with normally formed soft palates. Fifteen volunteers matched for age and sex with normal palates, who had not had total uvulectomy, were used as controls. Four assessment techniques were used: Air escape, with modified tongue anchor technique; Production of speech sounds; Transnasal nasopharyngoscopy; and Radiological screening. Even though Azzam and Kuehn (1977) have stressed the importance of the musculus uvulae in velopharyngeal closure, all assessments showed that partial excision of the musculus uvulae, as in total uvulectomy, has no statistically significant effect on the velopharyngeal status in subjects with a normally formed soft palate.

We report an anesthetic management of the ex-utero intrapartum treatment (EXIT) procedure performed in a fetus with giant epignathus due to laryngeal atresia at 28 weeks' gestation. Anesthesia of the mother was induced with thiamylal and vecuronium, and maintained with 4% sevoflurane in 100% oxygen before delivery. Sevoflurane provided excellent uterine relaxation. To maintain the arterial pressure, the patient received acetate Ringer and ephedrine 4mg. After hysterotomy, a pulse oxymeter and an ultrasound transducer were applied to monitor fetal Sp(O2) and heart rate. No anesthetic agents were injected into the fetus in addition to transplacental sevoflurane. Tracheostomy was performed on the fetus by pediatric surgeons on placental support. The uterine tone improved soon after discontinuing sevoflurane, intramyometrial injection of oxytocin and ergometrine infusion after delivery. Excision of the tumor was performed on day 2 of life. Pediatric surgeons tried to excise it totally, but it was hard to differentiate the tumor from the normal tissue, and partial excision was performed. After the excision, the neonate weighed 944 g and excised specimen weighed 253 g. Though the neonate was immature and the tumor was very large, no perioperative complications were associated with EXIT and the tumor excision.

Gynecomastia is a common aesthetic problem faced by men with reported incidence as high as 65% with serious psychosocial impact. Although various techniques of liposculpture combined with glandular excision is the standard of treatment, many of the glandular excision techniques have inherent limitations and complications such as leaving a long scar, long operative time, contour abnormalities, and increased risk of hematoma. Here, we describe an innovative "the orange peel excision of gland (OPEG) technique" which overcomes these limitations with excellent cosmetic results. A total of 38 breasts were operated in 20 patients (18 bilateral and 2 unilateral). All the patients underwent suction-assisted liposuction and glandular excision under general anesthesia by our OPEG technique. The average operative time per breast was 60 minutes. One patient had a small hematoma which did not require evacuation. The patient satisfaction rate was 95%. The technique has reduced operative time and avoids residual gland and hematoma with excellent aesthetic outcome.

CO2 laser versus cold steel margin analysis following endoscopic excision of glottic cancer

PubMed Central

2014-01-01

Objective To compare the suitability of CO2 laser with steel instruments for margin excision in transoral laser microsurgery. Methods Prospective randomized blinded study. Patients with glottic cancer undergoing laser resection were randomized to margin excision by either steel instruments or CO2 laser. Margins were analyzed for size, interpretability and degree of artifact by a pathologist who was blinded to technique. Results 45 patients were enrolled in the study with 226 total margins taken. 39 margins taken by laser had marked artifact and 0 were uninterpretable. 20 margins taken by steel instruments had marked artifact, and 2 were uninterpretable. Controlling for margin size, the laser technique was associated with increasing degrees of margin artifact (p = 0.210), but there was no difference in crude rates of uninterpretability (p = 0.24). Conclusion Laser margin excision is associated with a greater degree of artifact than steel instrument excision, but was not associated with higher rate of uninterpretability. PMID:24502856

Surgical excision has been an effective treatment for gynaecomastia. Recently, there has been a shift from the open approach to minimally invasive techniques. In this report we describe our technique which includes endoscopic excision and/or liposuction of gynaecomastia via a single lateral chest wall incision. Between May 2007 and April 2010, a total of 12 gynaecomastia patients were treated with liposuction and/or endoscopic excision. Patients were divided into 3 groups: group I; liposuction only, group II; endoscopic excision plus liposuction and group III; endoscopic excision only. One 15 mm incision was made laterally at the anterior axillary line. A vacuum assisted liposuction removing the fatty tissue was performed. Then endoscopic excision of the remaining fibroglandular tissue was done under vision through the same incision. The parynchyma was then dissected into small pieces and pulled out. Group I had liposuction only (n = 4), group II had liposuction combined with endoscopic excision (n = 7) (58%) while group III had endoscopic excision only (n = 1). The mean operative time for liposuction and endoscopic excision was 58 min for each side. Mean hospital stay was 1.4 days. Postoperative complications included infection with abscess formation and one patient had seroma. Mean follow-up was 56 weeks. Eleven out of twelve patients (92%) were satisfied with their results. Long-term follow-up showed that results were stable over time, and no revisions were necessary. Endoscopic excision of gynaecomastia through a single lateral chest wall incision is a minimally invasive effective and safe technique for the management of gynaecomastia, with excellent aesthetic results and an acceptable complication rate.

A global assessment of gross and net land change dynamics for current conditions and future scenarios

2018-05-01

The consideration of gross land changes, meaning all area gains and losses within a pixel or administrative unit (e.g. country), plays an essential role in the estimation of total land changes. Gross land changes affect the magnitude of total land changes, which feeds back to the attribution of biogeochemical and biophysical processes related to climate change in Earth system models. Global empirical studies on gross land changes are currently lacking. Whilst the relevance of gross changes for global change has been indicated in the literature, it is not accounted for in future land change scenarios. In this study, we extract gross and net land change dynamics from large-scale and high-resolution (30-100 m) remote sensing products to create a new global gross and net change dataset. Subsequently, we developed an approach to integrate our empirically derived gross and net changes with the results of future simulation models by accounting for the gross and net change addressed by the land use model and the gross and net change that is below the resolution of modelling. Based on our empirical data, we found that gross land change within 0.5° grid cells was substantially larger than net changes in all parts of the world. As 0.5° grid cells are a standard resolution of Earth system models, this leads to an underestimation of the amount of change. This finding contradicts earlier studies, which assumed gross land changes to appear in shifting cultivation areas only. Applied in a future scenario, the consideration of gross land changes led to approximately 50 % more land changes globally compared to a net land change representation. Gross land changes were most important in heterogeneous land systems with multiple land uses (e.g. shifting cultivation, smallholder farming, and agro-forestry systems). Moreover, the importance of gross changes decreased over time due to further polarization and intensification of land use. Our results serve as an empirical database for land change dynamics that can be applied in Earth system models and integrated assessment models.

Laparoscopic complete mesocolic excision with central vascular ligation in right colon cancer: Long-term oncologic outcome between mesocolic and non-mesocolic planes of surgery.

To analyze our experience in translating the concept of total mesorectal excision to "no-touch" complete removal of an intact mesocolonic envelope (complete mesocolic excision), along with central vascular ligation and apical node dissection, in the surgical treatment of right-sided colonic cancers, comparing "mesocolic" to less radical "non-mesocolic" planes of surgery in respect to quality of the surgical specimen and long-term oncologic outcome. A total of 115 patients with right-sided colonic cancers were retrospectively enrolled from 2008 to 2013 and operated on following the intent of minimally invasive complete mesocolic excision with central vascular ligation. Morbidity and mortality were 22.6% and 1.7%, respectively. Mesocolic, intramesocolic, and muscularis propria planes of resection were achieved in 65.2%, 21.7%, and 13% of cases, respectively, with significant impact for mesenteric plane of surgery on R0 resection rate (97.3%), circumferential resection margin <1 mm (2.6%), and consequent survival advantage (82.6% at 5 years) when compared to muscularis propria plane of surgery, with R0 resection rate and overall survival falling to 72% and 60%, respectively, and with circumferential resection margin <1 mm raising to 33.3%, all being statistically significant. Stratifying patients for stage of disease, laparoscopic complete mesocolic excision with central vascular ligation significantly impacted survival in patients with stage II, IIIA/B, and in a subgroup of IIIC patients with negative apical nodes. In our experience, minimally invasive complete mesocolic excision with central vascular ligation allows for both safety and higher quality of surgical specimens when compared to less radical intramesocolic or muscularis propria planes of "standard" surgery, significantly impacting loco-regional control and thus overall survival. © The Finnish Surgical Society 2014.

The management of benign intraductal papilloma (IDP) without atypia diagnosed on core needle biopsy (CNB) remains controversial. This study was performed to evaluate the rate of upgrading to malignancy or high-risk lesions after excision and to identify factors associated with upgrading using a large series of benign IDP cases without atypia. We included patients who were diagnosed as having benign IDP without atypia on CNB and underwent surgical or vacuum-assisted excision between 2010 and 2015. We analyzed the clinical, radiologic, and histopathologic features of IDPs that were upgraded to malignancy or high-risk lesions after excision. A total of 511 benign IDPs without atypia diagnosed via CNB were identified, of which 398 cases were treated with excision. After reviewing these cases, four cases of high-risk lesions in adjacent tissue on CNB, two cases which were revealed as papilloma with atypia, and nine cases of malignancy in the same breast were excluded. In the remaining 383 cases, the rate of upgrading to malignancy and high-risk lesions after excision was 0.8% and 4.4%, respectively. The presence of concurrent contralateral breast cancer, the presence of symptoms, and multifocality were factors significantly associated with upgrading to malignancy on subsequent excision. Surgical excision rather than vacuum-assisted excision was significantly associated with upgrading to high-risk lesions or malignancy. The rate of upgrading to malignancy for benign IDP without atypia was very low, suggesting that close clinical and radiologic observation may be sufficient for patients with benign IDP without atypia on CNB under proper settings.

2018-01-01

Background: The Ewing sarcoma peripheral PNET (ES-pPNET) is very rare small round cell tumour that involves the CNS as either a primary dural neoplasm or by direct extension from contiguous bone or soft tissue. Materials and Methods: Biopsy proven cases of intracranial ES/pPNET with orbital involvement operated during Jan 2010-Jan 2014 were retrospectively included and their clinical data, operative and histological findings were reviewed from institutional oncology register. Results: seven patients (4 males; 3 female) were studied with mean age at presentation of 13 years. Six patients had orbital involvement in one or other form. Surgical excision was gross total in five, near total in one, and subtotal in one patient. All patients received adjuvant therapy, only chemotherapy in 2, only Radiotherapy in four, both in one. MRI characteristics were studied in six patients. Four patients died with average survival of 33.2 months and three patients are having Progression free survival of average 23.3 months. Conclusions: The EWS-pPNET is very rare tumour and very poorly described in literature. These tumours are showing special predilection for the frontotemporal dura and erode through the flat bone of cranium like orbital roof and lateral wall of the orbit. These tumours are aggressive, multi compartmental, vascular and very rapidly growing, so missing or overlooking the primary symptoms of dural stretching/bony involvement leads to delay in management and poor outcome.

Managing Recurrence in Intraarticular Melorheostosis Involving the Knee Joint: A Case Report

PubMed Central

John, Bobby; Sharma, Anirudh; Pandey, Ritesh A

2017-01-01

Introduction: Melorheostosis is a rare benign sclerosing dysplasia affecting bone, which causes significant morbidity in the form of pain and restriction of joint movement. Treatment options are varied, and recurrence is common after surgical treatment. Choosing the most appropriate treatment option in the management of a recurrent case is challenging, with very little supporting evidence in literature owing to the rarity of the disease. We hereby present a case of recurrent melorheostosis involving the knee; discuss treatment options and the rationale of our treatment. Case Report: We present the case of a 42-year-old female who was operated at our institution previously 7 years ago for melorheostosis of her left knee and had undergone excision of intrarticular hyperostotic masses. However, pain and limitation of motion recurred in the operated knee 4 years later, and radiographs and computed tomography revealed a mineralized mass situated behind the patella in the patellofemoral joint. She was treated with repeat open excision of the mass and put on a regimen of physiotherapy and bisphosphonates. Conclusion: Open excision of symptomatic hyperostotic or mineralized soft tissue masses is perhaps the favored treatment option in such cases, the other options being arthroscopic excision and total knee arthroplasty. Limited knee motion and size of the mass often make arthroscopy an unfeasible option. Total knee arthroplasty should be reserved for cases with significant flexion contractures of the knee, or where multiple excisions have failed. PMID:29242791

The family needs of parents of preschool children with cerebral palsy: the impact of child's gross motor and communications functions.

PubMed

Bertule, Dace; Vetra, Anita

2014-01-01

An understanding of the needs of families of preschool children with cerebral palsy (CP) is of essential importance if efficient and cost-effective services are to be provided to them. The aims of this study were to identify the most frequently expressed needs of families with preschool children with CP; differences in the amount and types of family needs based on the child's gross motor function and communication function level; and the impact of the child's gross motor function and communication function level on the type and amount of family needs. A total of 227 parents of preschool children with CP completed a modified version of the Family Needs Survey and a demographic questionnaire. Children's gross motor function level and communication function level was classified using the Gross Motor Function Classification System (GMFCS) and the Communication Function Classification System (CFCS), respectively. The total number of family needs differed based on GMFCS and CFCS levels. Children's GMFCS and CFCS level were not significant predictors of overall family needs (adjusted R(2)=0.163). In this model the GMFCS level of children did not account for the total number of family needs, while the CFCS level did. Child's limitations in terms of communication and gross motor functions must be taken into consideration when planning services for families with preschool children with CP.

Mobilization of the rectum: anatomic concepts and the bookshelf revisited.

PubMed

Chapuis, Pierre; Bokey, Les; Fahrer, Marius; Sinclair, Gael; Bogduk, Nikolai

2002-01-01

Sound surgical technique is based on accurate anatomic knowledge. In surgery for cancer, the anatomy of the perirectal fascia and the retrorectal plane is the basis for correct mobilization of the rectum to ensure clear surgical margins and to minimize the risk of local recurrence. This review of the literature on the perirectal fascia is based on a translation of the original description by Thoma Jonnesco and a later account by Wilhelm Waldeyer. The Jonnesco description, first published in 1896 in French, is compared with the German account of 1899. These were critically analyzed in the context of our own and other techniques of mobilizing the rectum. Mobilization of the rectum for cancer can be performed along anatomic planes with minimal blood loss, preservation of the pelvic autonomic nerves and a low prevalence of local recurrence. Different techniques including total mesorectal excision are based on the same anatomic principles, however, popular words have been used to replace accepted, established terminology. In particular, the description of total mesorectal excision has been confusing because of its emphasis on the words "total" and "mesorectum." The use of the word "mesorectum" anatomically is inaccurate and the implication that total excision of all the perirectal fat contained within the perirectal fascia "en bloc" in all patients with rectal cancer will minimize local recurrence remains contentious.

Purpose The management of benign intraductal papilloma (IDP) without atypia diagnosed on core needle biopsy (CNB) remains controversial. This study was performed to evaluate the rate of upgrading to malignancy or high-risk lesions after excision and to identify factors associated with upgrading using a large series of benign IDP cases without atypia. Methods We included patients who were diagnosed as having benign IDP without atypia on CNB and underwent surgical or vacuum-assisted excision between 2010 and 2015. We analyzed the clinical, radiologic, and histopathologic features of IDPs that were upgraded to malignancy or high-risk lesions after excision. Results A total of 511 benign IDPs without atypia diagnosed via CNB were identified, of which 398 cases were treated with excision. After reviewing these cases, four cases of high-risk lesions in adjacent tissue on CNB, two cases which were revealed as papilloma with atypia, and nine cases of malignancy in the same breast were excluded. In the remaining 383 cases, the rate of upgrading to malignancy and high-risk lesions after excision was 0.8% and 4.4%, respectively. The presence of concurrent contralateral breast cancer, the presence of symptoms, and multifocality were factors significantly associated with upgrading to malignancy on subsequent excision. Surgical excision rather than vacuum-assisted excision was significantly associated with upgrading to high-risk lesions or malignancy. Conclusion The rate of upgrading to malignancy for benign IDP without atypia was very low, suggesting that close clinical and radiologic observation may be sufficient for patients with benign IDP without atypia on CNB under proper settings.

Purpose: The aims of this study were to determine the changes in breast and excision cavity volumes after whole-breast irradiation and the adequacy of using the surgical scar to guide boost planning. Methods and Materials: A total of 30 women consecutively treated for 31 breast cancers were included in this study. Simulation CT scans were performed before and after whole-breast irradiation. CT breast volumes were delineated using clinically defined borders. Excision cavity volumes were contoured based on surgical clips, the presence of a hematoma, and/or other surgical changes. Hypothetical electron boost plans were generated using the surgical scar with amore » 3-cm margin and analyzed for coverage. Results: The mean CT breast volumes were 774 and 761 cc (p = 0.22), and the excision cavity volumes were 32.1 and 25.1 cc (p < 0.0001), before and after 40 Gy (39-42 Gy) of whole-breast irradiation, respectively. The volume reduction in the excision cavity was inversely correlated with time elapsed since surgery (R = 0.46, p < 0.01) and body weight (R = 0.50, p < 0.01). The scar-guided hypothetical plans failed to cover the excision cavity adequately in 62% and 53.8% of cases using the pretreatment and postradiation CTs, respectively. Per the hypothetical plans, the minimum dose to the excision cavity was significantly lower for tumors located in the inner vs. outer quadrants (p = 0.02) and for cavities >20 cc vs. <20 cc (p = 0.01). Conclusions: This study demonstrates a significant reduction in the volume of the excision cavity during whole-breast irradiation. Scar-guided boost plans provide inadequate coverage of the excision cavity in the majority of cases.« less

We aimed to investigate the role of surgical excision in treating granulomatous lobular mastitis. We performed a retrospective chart review of patients with granulomatous lobular mastitis treated from March 2008 to March 2014. We analyzed clinical features and therapeutic modalities and compared the patient outcomes based on treatment. During the study period, a total of 34 patients were diagnosed with granulomatous lobular mastitis and treated. Initial treatments included wide excision (18), oral steroids after incision and drainage (14), and antibiotic therapy (2). The patients receiving only antibiotic therapy showed no improvement after 1 month and wide excision was then performed. Wide excision resulted in nine case of delayed wound healing with fistula. These patients were treated with oral steroids for 1.5-5 months, with subsequent improvement. Overall, 11 out of 20 patients who had underwent wide excision showed improvement without additional treatment. Fourteen patients who had initially received oral steroids for 1 to 6 months (average, 2.8 months) after incision and drainage showed complete remission. During the median follow-up period with 45.5 months (range, 22-98 months), six patients (17.6%) experienced recurrence. Wide excision group experienced recurrence in five (25%) and steroid and drainage group experienced recurrence in one (7.1%). All six recurrences responded to additional steroid therapy for average 3.5 months. Most wide excision group left extensive breast scarring with deformation that was not in steroid and drainage group. Wide excision resulted high recurrence than steroid and drainage group and left extensive scarring. Steroid therapy with or without abscess drainage may be the first choice of treatment for majority cases with granulomatous lobular mastitis.

Inflammatory Myofibroblastic Tumour (IMT) or 'pseudotumour' of the kidney is a rare benign tumour of unknown aetiology affecting mostly young adults. A subset of IMT is neoplastic and harbours translocations of activin receptor-like kinase-1 (ALK-1) gene and can recur or rarely metastasize. Presentation varies from an incidentaloma to gross haematuria. Clinical examination and radiological investigations are usually inconclusive. Often, biopsy is inconclusive necessitating a management similar to that of Renal Cell Cancer (RCC). Diagnosis is based on immunohistochemistry. We are reporting a case of IMT in a 50-year-old male patient who presented with left flank mass which on evaluation was suggestive of left renal cell carcinoma. Excision of the tumour, histopathological examination and Immunohistochemistry proved the tumour to be IMT.

Intra-operative ultrasound-based augmented reality guidance for laparoscopic surgery.

In laparoscopic surgery, the surgeon must operate with a limited field of view and reduced depth perception. This makes spatial understanding of critical structures difficult, such as an endophytic tumour in a partial nephrectomy. Such tumours yield a high complication rate of 47%, and excising them increases the risk of cutting into the kidney's collecting system. To overcome these challenges, an augmented reality guidance system is proposed. Using intra-operative ultrasound, a single navigation aid, and surgical instrument tracking, four augmentations of guidance information are provided during tumour excision. Qualitative and quantitative system benefits are measured in simulated robot-assisted partial nephrectomies. Robot-to-camera calibration achieved a total registration error of 1.0 ± 0.4 mm while the total system error is 2.5 ± 0.5 mm. The system significantly reduced healthy tissue excised from an average (±standard deviation) of 30.6 ± 5.5 to 17.5 ± 2.4 cm 3 ( p < 0.05) and reduced the depth from the tumor underside to cut from an average (±standard deviation) of 10.2 ± 4.1 to 3.3 ± 2.3 mm ( p < 0.05). Further evaluation is required in vivo, but the system has promising potential to reduce the amount of healthy parenchymal tissue excised.

Increasing excise taxes on cigarettes in California: a dynamic simulation of health and economic impacts.

PubMed

Ahmad, Sajjad

2005-07-01

California raised cigarette excise taxes in 1999, and may generate additional health and economic benefits by raising them further. A dynamic computer simulation model follows births, deaths, migration, aging, and changes in smoking status for the entire population of California over 75 years to estimate the cumulative health and economic outcomes of these changes under several excise tax rate conditions (up to 100% price increase). A 20% tax-induced cigarette price increase would reduce smoking prevalence from 17% to 11.6% with large gains in cumulative life years (14 million) and QALY's (16 million) over 75 years. Total spending on cigarettes by consumers would increase by 270 million dollars in that span (all going to tax revenue), and those who reduce the number of years spent as a smoker would spend 12.5 billion dollars less on cigarettes. Total smoking-related medical costs would drop by 188 billion dollars. These benefits increase greatly with larger tax increases, with which tax revenues continue to rise even as smoking prevalence falls. Even considering benefits from the 1999 increase, California has not yet maximized the potential of excise taxes to lessen the negative impacts of smoking. Additional tax increases would provide added health benefits and revenue to the state.

Objective: To evaluate the impact of cigarette excise tax up-regulation on the retail price of cigarettes in 2015. Methods: Nominal and real price of selected cigarette varieties were calculated with data from Tobacco Retail Price Monitoring Project, which was conducted in 10 cities of China from 2013 to 2015. The trend of the cigarette prices changing was analyzed with annual data. Results: A total of 352 varieties of cigarettes were surveyed during the three years. The nominal price of these cigarettes did not change significantly from 2013 to 2014. Compared with nominal price of 2014, the price of 286 varieties increased and the price of 10 most popular varieties increased from 0.6 % to 7.4 % after cigarette excise tax increased, but the actual prices had both rise and fall compared with 2013. Conclusions: Cigarette excise tax raise in 2015 had influence on the retail price of cigarettes. But the increase in retail price was very limited, if factors including inflation and purchasing power are taken into consideration. Therefore, the influence of 2015 cigarette excise tax raise on tobacco control needs further evaluation.

Background: Gynecomastia is a deformity of male chest. Treatment of gynecomastia varied from direct surgical excision to other techniques (mainly liposuction) to a combination of both. Skin excision is done according to the grade. In this study, experience of using liposuction adjuvant to surgical excision was described. Patients and methods: Between September 2012 and April 2015, a total of 14 patients were treated with liposuction and surgical excision through a periareolar incision. Preoperative evaluation was done in all cases to exclude any underlying cause of gynecomastia. Results: All fourteen patients were treated bilaterally (28 breast tissues). Their ages ranged between 13 and 33 years. Two patients were classified as grade I, and four as grade IIa, IIb or III, respectively. The first 3 patients showed seroma. Partial superficial epidermolysis of areola occurred in 2 cases. Superficial infection of incision occurred in one case and was treated conservatively. Conclusion: All grades of gynecomastia were managed by the same approach. Skin excision was added to a patient that had severe skin excess with limited activity and bad skin complexion. No cases required another setting or asked for 2nd opinion. PMID:26955509

Bloomfield, Ian; Van Dalen, Roelof; Lolohea, Simione; Wu, Linus

2018-06-01

Transanal endoscopic microsurgery (TEMS) is a proven alternative therapy to either radical surgery or endoscopic mucosal resection for rectal neoplasms. It has proven benefits with lower morbidity and mortality compared with total mesorectal excision, and a lower local recurrence rate when compared to endoscopic mucosal techniques. A retrospective data collection of TEMS procedures performed through Waikato District Health Board, New Zealand, from 2010 to 2015 was conducted. Supportive follow-up data were sourced from patient records and from local centres around New Zealand. A total of 137 procedures were performed over the study period, with five being repeat procedures. Procedures were mostly performed for benign lesions (66.4%) with an overall complication rate of 15.3%, only five of which were Clavien-Dindo grade III (3.6%). Our local recurrence rate after resection of benign lesions was 5.1%. Our data set demonstrates the TEMS procedure to be safe compared to radical resection (total mesorectal excision) for sessile rectal lesions. Close endoscopic follow-up is recommended, especially for close or incomplete margins. Good therapeutic results can be obtained for appropriately selected early malignant lesions. TEMS provides better oncological results than endoscopic mucosal resection or transanal excision. © 2017 Royal Australasian College of Surgeons.

The gold standard for curative treatment of locally advanced rectal cancer involves radical resection with a total mesorectal excision (TME). TME is the most effective treatment strategy to reduce local recurrence and improve survival outcomes regardless of the surgical platform used. However, there are associated morbidities, functional consequences, and quality of life (QoL) issues associated with TME; these risks must be considered during the modern-day multidisciplinary treatment for rectal cancer. This has led to the development of new surgical techniques to improve patient, oncologic, and QoL outcomes. In this work, we review the evolution of TME to the transanal total mesorectal excision (TaTME) through more traditional minimally invasive platforms. The review the development, safety and feasibility, proposed benefits and risks of the procedure, implementation and education models, and future direction for research and implementation of the TaTME in colorectal surgery. While satisfactory short-term results have been reported, the procedure is in its infancy, and long term outcomes and definitive results from controlled trials are pending. As evidence for safety and feasibility accumulates, structured training programs to standardize teaching, training, and safe expansion will aid the safe spread of the TaTME. PMID:29588809

2016-08-01

In this study, we compare the indications for re-excision, the findings of additional tumor in the re-excision specimen as they relate to margin status, and costs associated with re-excision based on recent new consensus statements. A retrospective analysis was performed on 462 patients with invasive breast carcinoma who underwent at least one lumpectomy between January 2011 and December 2013. Postoperative data was analyzed based on where additional disease was found, as it relates to the margin status of the initial lumpectomy and the additional direct costs associated with additional procedures. Of the 462 patients sampled, 149 underwent a re-excision surgery (32.2%). Four patients underwent mastectomy as their second operation. In the 40 patients with additional disease found on re-excision, 36 (90.0%) of them had a positive margin on their initial lumpectomy. None of the four mastectomy patients had residual disease. The mean cost of the initial lumpectomy for all 462 patients was $2118.01 plus an additional $1801.92 for those who underwent re-excision. A positive margin was most predictive of finding residual tumor on re-excision as would be expected. Using old criteria only 0.07% (4/61) of patients who had undergone re-excision with a 'clear' margin, had additional tumor found, at a total cost of $106,354.11. Thus, the new consensus guidelines will lead to less overall cost, at no clinical risk to patients while reducing a patient's surgical risk and essentially eliminating delays in adjuvant care.

Radium-226 and radium-228 in shallow ground water, southern New Jersey

Concentrations of total radium (the sum of radium-226 and radium-228) and gross alpha-particle activities in drinking water that exceed the U.S. Environmental Protection Agency (USEPA) Maximum Contaminant Levels (MCLs) are known to cause cancer. Results of investigations by the U.S. Geological Survey (USGS) in cooperation with the New Jersey Department of Environmental Protection (NJDEP) indicate that concentrations of total radium in water samples from 33 percent of 170 wells in the Kirkwood-Cohansey aquifer system in southern New Jersey exceeded the MCL of 5 pCi/L (picocuries per liter) (fig. 1). Wells containing water in which concentrations of total radium were greater than the MCL typically are found where the Bridgeton Formation crops out, in or near an agricultural area, where ground water is acidic (pH less than 5), and where nitrate concentrations generally exceed 5 mg/L (milligrams per liter). Leaching of nitrogen, calcium, and magnesium from agricultural chemicals (fertilizer, lime) applied to cropland may increase the mobility of radium in ground water. Gross alphaparticle activities exceeded the USEPA MCL of 15 pCi/L in water from 14 percent of 127 wells. A statistically significant 2:1 ratio between gross alpha-particle activity and concentration of total radium indicates that gross alpha-particle activity can be used as a screening tool to predict the presence of water that may have a high total-radium concentration.

The gross morphology and histochemistry of respiratory muscles in bottlenose dolphins, Tursiops truncatus.

Cotten, Pamela B; Piscitelli, Marina A; McLellan, William A; Rommel, Sentiel A; Dearolf, Jennifer L; Pabst, D Ann

2008-12-01

Most mammals possess stamina because their locomotor and respiratory (i.e., ventilatory) systems are mechanically coupled. These systems are decoupled, however, in bottlenose dolphins (Tursiops truncatus) as they swim on a breath hold. Locomotion and ventilation are coupled only during their brief surfacing event, when they respire explosively (up to 90% of total lung volume in approximately 0.3 s) (Ridgway et al. 1969 Science 166:1651-1654). The predominantly slow-twitch fiber profile of their diaphragm (Dearolf 2003 J Morphol 256:79-88) suggests that this muscle does not likely power their rapid ventilatory event. Based on Bramble's (1989 Amer Zool 29:171-186) biomechanical model of locomotor-respiratory coupling in galloping mammals, it was hypothesized that locomotor muscles function to power ventilation in bottlenose dolphins. It was further hypothesized that these muscles would be composed predominantly of fast-twitch fibers to facilitate the bottlenose dolphin's rapid ventilation. The gross morphology of craniocervical (scalenus, sternocephalicus, sternohyoid), thoracic (intercostals, transverse thoracis), and lumbopelvic (hypaxialis, rectus abdominis, abdominal obliques) muscles (n = 7) and the fiber-type profiles (n = 6) of selected muscles (scalenus, sternocephalicus, sternohyoid, rectus abdominis) of bottlenose dolphins were investigated. Physical manipulations of excised thoracic units were carried out to investigate potential actions of these muscles. Results suggest that the craniocervical muscles act to draw the sternum and associated ribs craniodorsally, which flares the ribs laterally, and increases the thoracic cavity volume required for inspiration. The lumbopelvic muscles act to draw the sternum and caudal ribs caudally, which decreases the volumes of the thoracic and abdominal cavities required for expiration. All muscles investigated were composed predominantly of fast-twitch fibers (range 61-88% by area) and appear histochemically poised for rapid contraction. These combined results suggest that dolphins utilize muscles, similar to those used by galloping mammals, to power their explosive ventilation. (c) 2008 Wiley-Liss, Inc.

Correlation of ultrasound appearance, gross anatomy, and histology of the femoral nerve at the femoral triangle.

Lonchena, Tiffany K; McFadden, Kathryn; Orebaugh, Steven L

2016-01-01

Correlation between ultrasound appearance, gross anatomic characteristics, and histologic structure of the femoral nerve (FN) is lacking. Utilizing cadavers, we sought to characterize the anatomy of the FN, and provide a quantitative measure of its branching. We hypothesize that at the femoral crease, the FN exists as a group of nerve branches, rather than a single nerve structure, and secondarily, that this transition into many branches is apparent on ultrasonography. Nineteen preserved cadavers were investigated. Ultrasonography was sufficient to evaluate the femoral nerve in nine specimens; gross dissection was utilized in all 19. Anatomic characteristics were recorded, including distances from the inguinal ligament to femoral crease, first nerve branch, and complete arborization of the nerve. The nerves from nine specimens were excised for histologic analysis. On ultrasound, the nerve became more flattened, widened, and less discrete as it coursed distally. Branching of the nerve was apparent in 12 of 18 images, with mean distance from inguinal ligament of 3.9 (1.0) cm. However, upon dissection, major branching of the femoral nerve occurred at 3.1 (1.0) cm distal to the inguinal ligament, well proximal to the femoral crease. Histologic analysis was consistent with findings at dissection. The femoral nerve arborizes into multiple branches between the inguinal ligament and the femoral crease. Initial branching is often high in the femoral triangle. As hypothesized, the FN exists as a closely associated group of nerve branches at the level of the femoral crease; however, the termination of the nerve into multiple branches is not consistently apparent on ultrasonography.

Rett syndrome is a pervasive neurodevelopmental disorder associated with a pathogenic mutation on the MECP2 gene. Impaired movement is a fundamental component and the Rett Syndrome Gross Motor Scale was developed to measure gross motor abilities in this population. The current study investigated the validity and reliability of the Rett Syndrome Gross Motor Scale. Video data showing gross motor abilities supplemented with parent report data was collected for 255 girls and women registered with the Australian Rett Syndrome Database, and the factor structure and relationships between motor scores, age and genotype were investigated. Clinical assessment scores for 38 girls and women with Rett syndrome who attended the Danish Center for Rett Syndrome were used to assess consistency of measurement. Principal components analysis enabled the calculation of three factor scores: Sitting, Standing and Walking, and Challenge. Motor scores were poorer with increasing age and those with the p.Arg133Cys, p.Arg294* or p.Arg306Cys mutation achieved higher scores than those with a large deletion. The repeatability of clinical assessment was excellent (intraclass correlation coefficient for total score 0.99, 95% CI 0.93-0.98). The standard error of measurement for the total score was 2 points and we would be 95% confident that a change 4 points in the 45-point scale would be greater than within-subject measurement error. The Rett Syndrome Gross Motor Scale could be an appropriate measure of gross motor skills in clinical practice and clinical trials.

Gross domestic product and health expenditure associated with incidence, 30-day fatality, and age at stroke onset: a systematic review.

PubMed

Sposato, Luciano A; Saposnik, Gustavo

2012-01-01

Differences in definitions of socioeconomic status and between study designs hinder their comparability across countries. We aimed to analyze the correlation between 3 widely used macrosocioeconomic status indicators and clinical outcomes. We selected population-based studies reporting incident stroke risk and/or 30-day case-fatality according to prespecified criteria. We used 3 macrosocioeconomic status indicators that are consistently defined by international agencies: per capita gross domestic product adjusted for purchasing power parity, total health expenditures per capita at purchasing power parity, and unemployment rate. We examined the correlation of each macrosocioeconomic status indicator with incident risk of stroke, 30-day case-fatality, proportion of hemorrhagic strokes, and age at stroke onset. Twenty-three articles comprising 30 population-based studies fulfilled the eligibility criteria. Age-adjusted incident risk of stroke using the standardized World Health Organization World population was associated to lower per capita gross domestic product adjusted for purchasing power parity (ρ=-0.661, P=0.027, R(2)=0.32) and total health expenditures per capita at purchasing power parity (ρ=-0.623, P=0.040, R(2)=0.26). Thirty-day case-fatality rates and proportion of hemorrhagic strokes were also related to lower per capita gross domestic product adjusted for purchasing power parity and total health expenditures per capita at purchasing power parity. Moreover, stroke occurred at a younger age in populations with low per capita gross domestic product adjusted for purchasing power parity and total health expenditures per capita at purchasing power parity. There was no correlation between unemployment rates and outcome measures. Lower per capita gross domestic product adjusted for purchasing power parity and total health expenditures per capita at purchasing power parity were associated with higher incident risk of stroke, higher case-fatality, a greater proportion of hemorrhagic strokes, and lower age at stroke onset. As a result, these macrosocioeconomic status indicators may be used as proxy measures of quality of primary prevention and acute care and considered as important factors for developing strategies aimed at improving worldwide stroke care.

Inflammatory myofibroblastic tumor (IMT) is a disease characterized by tumorous lesions consisting of myofibroblastic spindle cells and inflammatory cells that occur primarily in the soft tissues and viscera of children and young adults. Total excision is the most effective therapy. Steroids have been used to treat unresectable lesions with some success. We herein report a case of IMT involving the frontal bone accompanied by pachymeningitis. The tumor was characterized by an aggressive clinical course that was refractory to prednisolone. Performing total excision seemed difficult. Celecoxib and methotrexate were effective treatments. Our experience suggests the efficacy of celecoxib and methotrexate as alternatives for treating unresectable IMT.

A 77-year-old woman underwent metal-on-polyethylene total hip arthroplasty for osteoarthritis of the right hip at another institution. During surgery, the greater trochanter was broken and internal fixation was performed with a trochanteric cable grip reattachment. Although postoperative recovery was uneventful, approximately 6 years later, the patient had severe right hip pain with apparent swelling, and she was referred to the authors' institution. Plain radiographs showed evidence of severe osteolysis in the proximal femur and cable breakage; however, preoperative aspiration culture findings were negative for bacterial growth. Magnetic resonance imaging showed a well-circumscribed mass, presumed to be a pseudotumor. Serum cobalt and chromium levels were within normal limits, and the serum titanium level was high. During surgery, the mass was excised and removal of the cable system revealed a sharp deficit in the bare femoral stem. Gross surgical findings showed no obvious evidence of infection and no corrosion at the head-neck junction; therefore, all components were retained besides the cable system, which resulted in clinical recovery. All of the cultures from specimens were negative for bacterial growth, and histologic findings were compatible with a pseudotumor, such as histiocytes containing metal particles, abundant plasma cells, and CD8-positive cells. Quantitative analysis by inductively coupled plasma atomic emission spectrometry showed that the main source of metal debris in the pseudotumor was the femoral stem, which was made of titanium alloy, not the broken cable, which was made of cobalt-chromium alloy. The findings suggest that titanium particles can form symptomatic solid pseudotumors. Copyright 2016, SLACK Incorporated.

Effects of land use change on soil gross nitrogen transformation rates in subtropical acid soils of Southwest China.

Land use change affects soil gross nitrogen (N) transformations, but such information is particularly lacking under subtropical conditions. A study was carried out to investigate the potential gross N transformation rates in forest and agricultural (converted from the forest) soils in subtropical China. The simultaneously occurring gross N transformations in soil were quantified by a (15)N tracing study under aerobic conditions. The results showed that change of land use types substantially altered most gross N transformation rates. The gross ammonification and nitrification rates were significantly higher in the agricultural soils than in the forest soils, while the reverse was true for the gross N immobilization rates. The higher total carbon (C) concentrations and C / N ratio in the forest soils relative to the agricultural soils were related to the greater gross N immobilization rates in the forest soils. The lower gross ammonification combined with negligible gross nitrification rates, but much higher gross N immobilization rates in the forest soils than in the agricultural soils suggest that this may be a mechanism to effectively conserve available mineral N in the forest soils through increasing microbial biomass N, the relatively labile organic N. The greater gross nitrification rates and lower gross N immobilization rates in the agricultural soils suggest that conversion of forests to agricultural soils may exert more negative effects on the environment by N loss through NO3 (-) leaching or denitrification (when conditions for denitrification exist).

Stuck in Neutral: Stalled Progress in Statewide Comprehensive Smoke-Free Laws and Cigarette Excise Taxes, United States, 2000–2014

Introduction Increasing tobacco excise taxes and implementing comprehensive smoke-free laws are two of the most effective population-level strategies to reduce tobacco use, prevent tobacco use initiation, and protect nonsmokers from secondhand smoke. We examined state laws related to smoke-free buildings and to cigarette excise taxes from 2000 through 2014 to see how implementation of these laws from 2000 through 2009 differs from implementation in more recent years (2010–2014). Methods We used legislative data from LexisNexis, an online legal research database, to examine changes in statewide smoke-free laws and cigarette excise taxes in effect from January 1, 2000, through December 31, 2014. A comprehensive smoke-free law was defined as a statewide law prohibiting smoking in all indoor areas of private work sites, restaurants, and bars. Results From 2000 through 2009, 21 states and the District of Columbia implemented comprehensive smoke-free laws prohibiting smoking in work sites, restaurants, and bars. In 2010, 4 states implemented comprehensive smoke-free laws. The last state to implement a comprehensive smoke-free law was North Dakota in 2012, bringing the total number to 26 states and the District of Columbia. From 2000 through 2009, 46 states and the District of Columbia implemented laws increasing their cigarette excise tax, which increased the national average state excise tax rate by $0.92. However, from 2010 through 2014, only 14 states and the District of Columbia increased their excise tax, which increased the national average state excise tax rate by $0.20. Conclusion The recent stall in progress in enacting and implementing statewide comprehensive smoke-free laws and increasing cigarette excise taxes may undermine tobacco prevention and control efforts in the United States, undercutting efforts to reduce tobacco use, exposure to secondhand smoke, health disparities, and tobacco-related illness and death.

2018-06-26

To validate a new procedure for the three-dimensional (3D) estimation of total renal parenchyma volume (RPV) using a structured-light infrared laser sensor. To evaluate the accuracy of the sensor for assessing renal volume, we performed three experiments. Twenty freshly excised porcine kidneys were obtained. Experiment A, the water displacement method was used to obtain a determination of the RPV after immersing every kidney into 0.9% saline. Thereafter a structured sensor (Occipital, San Francisco, CA, USA) was used to scan the kidney. Kidney sample surface was presented initially as a mesh and then imported into MeshLab (Visual Computing Lab, Pisa, Italy) software to obtain the surface volume. Experiment B, a partial excision of the kidney with measurement of the excised volume and remnant was performed. Experiment C, a renorrhaphy of the remnant kidney was performed then measured. Bias and limits of agreement (LOA) were determined using the Bland-Altman method. Reliability was assessed using the intraclass correlation coefficient (ICC). Experiment A, the sensor bias was -1.95 mL (LOA: -19.5 to 15.59, R2= 0.410) with slightly overestimating the volumes. Experiment B, remnant kidney after partial excision and excised kidney volume were measured showing a sensor bias of -0.5 mL (LOA -5.34 to 4.20, R2= 0.490) and -0.6 mL (LOA: -1.97.08 to 0.77, R2= 0.561), respectively. Experiment C, the sensor bias was -0.89 mL (LOA -12.9 to 11.1, R2= 0.888). ICC was 0.9998. The sensor is a reliable method for assessing total renal volume with high levels of accuracy.

'Batman excision' of ventral skin in hypospadias repair, clue to aesthetic repair (point of technique).

PubMed

Hoebeke, P B; De Kuyper, P; Van Laecke, E

2002-11-01

In the hypospadiac penis the ventral skin is poorly developed, while dorsal skin is redundant. The classical Byars' flaps are a way to use the excess dorsal skin to cover the penile shaft. The appearance after Byars' flaps however is not natural. We use a more natural looking skin allocation with superior aesthetic results. The clue in this reconstruction is an inverted triangle shaped excision of ventral skin expanding over the edges of the hooded prepuce (which makes it look like Batman). After excision of the ventral skin it is possible to close the penile skin in the midline, thus mimicking the natural raphe. In case of preputial reconstruction the excised ventral skin makes the prepuce look more natural. The trend of further refining aesthetic appearance of the hypospadiac penis often neglects the penile skin reconstruction. A technique is presented by which the total penile appearances after surgery ameliorates due to better skin reconstruction.

Although the existing evidence suggests that there is no obviously superior conservative method for treating cervical intraepithelial neoplasia (CIN), one of the most widely used is the large loop excision of the transformation zone (LLETZ). A total of 897 women who were treated with LLETZ at our colposcopy clinic from 1989 to 2000 were retrospectively studied. Forty women did not have significant cervical pathology (4.5% over-treatment rate). Clear margins of excision were obtained in 748 (88.5%) of the 845 cases of CIN or microinvasive cancers. Treatment failure rates were 4.7% for clear margins and 26.8% for involved or uncertain. LLETZ is a fast and reliable method of treating CIN and microinvasive carcinoma. Generalized cauterization of the resulting crater should be avoided and satellite HPV lesions ablated. Involved margins have a higher treatmentfailure rate, therefore a larger excision is recommended as cervical craters regenerate. Treatment in pregnant women can be delayed until postpartum provided they have adequate surveillance during pregnancy.

this study was aimed at analyzing the immediate postoperative course in rectal cancer patients who underwent a low anterior resection of the rectum with total mesorectal excision. A retrospective study was carried out on a series of 75 patients operated between January 1, 2004 and December, 31 2010 at the 1lrd Surgical Unit of the Iasi "St. Spiridon" Hospital,. Low anterior resection of the rectum with total mesorectal excision was performed in all the patients. Data from medical files regarding the immediate postoperative course were analyzed. Neoadjuvant therapy was instituted in 32 patients. There were 28 mechanical colorectal anastomoses and 47 manual anastomoses. Protective ileostomy was performed in 46 cases, including I manual anastomosis and 35 mechanical anastomosis cases. Anastomotic fistulas occured in II patients (6 with manual suture and 5 with stapler). Wound complications were identified in 5 cases, while retraction of ileostomy in 2. Two patients died from anastomotic fistula causing abdominal sepsis and multiple organ failure. In both cases ileostomy was performed at the reintervention, concomitantly with drainage of the abdominal abscesses. Healing of the colorectal anastomosis remains the major problem with low anterior resection of the rectum. Protective ileostomy reduces the risk of serious complications in the event of anastomotic fistula.

A randomized phase II/III trial was started in May 2015 comparing perioperative versus postoperative chemotherapy with modified infusional fluorouracil and folinic acid with oxaliplatin for lower rectal cancer patients with suspected lateral pelvic node metastasis. The standard arm is total mesorectal excision or tumor-specific mesorectal excision with lateral pelvic node dissection (LND) followed by postoperative chemotherapy (modified infusional fluorouracil and folinic acid with oxaliplatin; 12 cycles). The experimental (perioperative chemotherapy) arm is six courses of modified infusional fluorouracil and folinic acid with oxaliplatin before and six courses after total mesorectal excision with lateral pelvic node dissection. The aim of this trial is to confirm the superiority of perioperative chemotherapy. A total of 330 patients will be enrolled over 7 years. The primary endpoint in Phase II part is proportion of R0 resection and that in Phase III part is overall survival. Secondary endpoints are progression-free survival, local progression-free survival, etc. This trial has been registered in the UMIN Clinical Trials Registry as UMIN000017603 [http://www.umin.ac.jp/ctr/index-j.htm]. © The Author 2016.

Transanal total mesorectal excision (TaTME) seems to be a valid alternative to the open or laparoscopic TME. Quality of the TME specimen is the most important prognostic factor in rectal cancer. This study shows the pathological results of the largest single-institution series published on TaTME in patients with mid and low rectal cancer. We conducted a retrospective cohort study of all consecutive patients with rectal cancer, treated by TaTME between November 2011 and June 2016. Patient data were prospectively included in a standardized database. Patients with all TNM stages of mid (5-10 cm from the anal verge) and low (0-5 cm from the anal verge) rectal cancer were included. A total of 186 patients were included. Tumor was in the mid and low rectum in, respectively, 62.9 and 37.1%. Neoadjuvant chemoradiotherapy was given in 62.4%, only radiotherapy in 3.2%, and only chemotherapy in 2.2%. Preoperative staging showed T1 in 3.2%, T2 in 20.4%, T3 in 67.7%, and T4 in 7.5%. Mesorectal resection quality was complete in 95.7% (n = 178), almost complete in 1.6% (n = 3), and incomplete in 1.1% (n = 2). Overall positive CRM (≤ 1 mm) and DRM (≤ 1 mm) were 8.1% (n = 15) and 3.2% (n = 6), respectively. The composite of complete mesorectal excision, negative CRM, and negative DRM was achieved in 88.1% (n = 155) of the patients. The median number of lymph nodes found per specimen was 14.0 (IQR 11-18). The present study showed good rates regarding total mesorectal excision, negative circumferential, and distal resection margins. As the specimen quality is a surrogate marker for survival, TaTME can be regarded as a safe method to treat patients with rectal cancer, from an oncological point of view.

This study was designed to investigate how the quality of life of patients with rectal cancer changes with time after laparoscopic total mesorectal excision. Patients completed the Medical Outcomes Study Short Form 36 and the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire and a colorectal-specific European Organisation for Research and Treatment of Cancer quality of life questionnaire before laparoscopic total mesorectal excision, on discharge from the hospital and at 3, 6, and 12 months postoperatively. Patients were treated by laparoscopic low anterior resection or laparoscopic abdominoperineal resection. Fifty-one patients (mean age, 64 years; 29 males (57 percent)) participated in this study, of whom 38 (75 percent) underwent laparoscopic low anterior resection and 13 (25 percent) laparoscopic abdominoperineal resection. Compared with preoperative scores on the Medical Outcomes Study Short Form 36, patients reported a deterioration in physical functioning (74 vs. 80; P = 0.009), and improved mental functioning (76 vs. 70; P = 0.007) at three months. Improvement in emotional well-being was reported both on the Medical Outcomes Study Short Form 36 (78 vs. 53; P = 0.006) and the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (84 vs. 69; P < 0.001). At one year, improvements in global quality of life (82 vs. 68; P = 0.001) and symptoms, such as fatigue (18 vs. 32; P < 0.001), pain (5 vs. 12; P = 0.009), and appetite loss (3 vs. 13; P = 0.01), were reported. Sexual functioning was worse from three months onward until one year after surgery (47 vs. 66; P = 0.004). Patients who underwent low anterior resection experienced less sexual dysfunction than patients after abdominoperineal resection (21 vs. 56; P = 0.004). One year after laparoscopic total mesorectal excision for rectal cancer, patients reported improvement in some important quality of life outcomes, including global quality of life, despite a decrease in sexual functioning.

Fifteen to twenty percent of patients with locally advanced rectal cancer have a clinical complete response after chemoradiation therapy. These patients can be offered nonoperative organ-preserving treatment, the so-called watch-and-wait policy. The main goal of this watch-and-wait policy is an anticipated improved quality of life and functional outcome in comparison with a total mesorectal excision, while maintaining a good oncological outcome. The aim of this study was to compare the quality of life of watch-and-wait patients with a matched-controlled group of patients who underwent chemoradiation and surgery (total mesorectal excision group). This was a matched controlled study. This study was conducted at multiple centers. The study population consisted of 2 groups: 41 patients after a watch-and-wait policy and 41 matched patients after chemoradiation and surgery. Patients were matched on sex, age, tumor stage, and tumor height. All patients were disease free at the moment of recruitment after a minimal follow-up of 2 years. Quality of life was measured by validated questionnaires covering general quality of life (Short Form 36, European Organization for Research and Treatment of Cancer QLQ-C30), disease-specific total mesorectal excision (European Organization for Research and Treatment of Cancer QLQ-CR38), defecation problems (Vaizey and low anterior resection syndrome scores), sexual problems (International Index of Erectile Function and Female Sexual Function Index), and urinary dysfunction (International Prostate Symptom Score). The watch-and-wait group showed better physical and cognitive function, better physical and emotional roles, and better global health status compared with the total mesorectal excision group. The watch-and-wait patients showed fewer problems with defecation and sexual and urinary tract function. This study only focused on watch-and-wait patients who achieved a sustained complete response for 2 years. In addition, this is a study with a limited number of patients and with quality-of-life measurements on nonpredefined and variable intervals after surgery. After a successful watch-and-wait approach, the quality of life was better than after chemoradiation and surgery on several domains. However, chemoradiation therapy on its own is not without long-term side effects, because one-third of the watch-and-wait patients experienced major low anterior resection syndrome symptoms, compared with 66.7% of the patients in the total mesorectal excision group.

Educator-led programs for physical activity and motor skill development show potential but few have been implemented and evaluated using a randomized controlled design. Furthermore, few educator-led programs have evaluated both gross motor skills and physical activity. Therefore, the aim of this study was to evaluate a gross motor skill and physical activity program for preschool children which was facilitated solely by childcare educators. A six-month 2-arm randomized controlled trial was implemented between April and September 2012 in four early childhood centers in Tasmania, Australia. Educators participated in ongoing professional development sessions and children participated in structured physical activity lessons and unstructured physical activity sessions. In total, 150 children were recruited from four centers which were randomized to intervention or wait-list control group. Six early childhood educators from the intervention centers were trained to deliver the intervention. Gross motor skills were assessed using the Test of Gross Motor Development (2nd edition) and physical activity was measured objectively using GT3X+ Actigraph accelerometers. No statistically significant differences were identified. However, small to medium effect sizes, in favor of the intervention group, were evident for four of the five gross motor skills and the total gross motor skill score and small to medium effect sizes were reported for all physical activity outcomes. This study highlights the potential of educator-led physical activity interventions and supports the need for further translational trials within the early childhood sector.

Craniofacial Neurofibromatosis is a benign but devastating disease. While the most common location of facial involvement is the orbito-temporal region, patients often present with significant mid-face deformities. We reviewed our experience with Craniofacial Neurofibromatosis from June 1981 to June 2011 and included patients with midface soft tissue deformities defined as gross alteration of nasal or upper lip symmetry. Data reviewed included the medical records and photobank. Over 30 years, 52 patients presented to and underwent surgical management for Craniofacial Neurofibromatosis at the Chang Gung Craniofacial Center. 23 patients (43%) demonstrated gross mid-facial deformities at initial evaluation. 55% of patients with lip deformities and 28% of patients with nasal deformities demonstrated no direct tumour involvement. The respective deformity was solely due to secondary gravitational effects from neurofibromas of the cheek subunit. Primary tumour infiltration of the nasal and/or labial subunits was treated with excision followed by various methods of reconstruction including lower lateral cartilage repositioning, forehead flaps, free flaps, and/or oral commissure suspension. Soft tissue deformities of the midface are very common in patients with Craniofacial Neurofibromatosis and profoundly affect overall aesthetic outcomes. Distinguishing primary from secondary involvement of the midface assists in surgical decision making. Copyright © 2013 European Association for Cranio-Maxillo-Facial Surgery.

The clinical outcomes of patients who have undergone total pelvic exenteration (TPE) for locally advanced primary colorectal cancer have not been satisfactory. For the last 13 years, we have performed layer-oriented, en bloc resection of tumor for which TPE is indicated, in the hope of improving postoperative outcomes. The clinical outcomes of these cases were retrospectively analyzed. A total of 54 patients who underwent TPE from 1986 to 2013 were retrospectively analyzed. Since 2002, a layer-oriented removal for clinical T4 colorectal cancer, as in T3 or less invasive tumors removed by total mesorectal excision, was applied to 23 cases for which TPE was indicated. Postoperative mortality, morbidity, overall survival (OS), and disease-free survival (DFS) were evaluated. On univariate analysis, good postoperative OS and DFS were associated with the layer-oriented operative maneuver, blood loss less than 2000 mL, negative nodal metastasis, and no preoperative radiation therapy. Male sex was the marginal determinant correlated with good OS and DFS. Depth of invasion to T3 was the marginal determinant correlated with good DFS. On multivariate analysis using the 4 factors identified on univariate analyses, the layer-oriented operative procedure was a significant determinant for both good OS and DFS, together with negative nodal metastases. Postoperative mortality and morbidity in the layer-oriented excision were acceptable. For primary colorectal cancers for which TPE is indicated, layer-oriented excision was a safe and effective procedure, and it may be recommended as one of the standard surgical approaches in TPE.

Breast surgery techniques: preoperative bracketing wire localization by surgeons.

2007-06-01

With the development of expertise in image guidance for breast surgery, many surgeons now perform preoperative wire localization themselves. Use of a single wire versus multiple wires to bracket a radiographic breast abnormality has previously been described, although benefits of this technique based on clinical outcomes such as margin status, tissue volume removed, and re-excision rates have not been established. This study is a retrospective analysis of wire-localized breast biopsies performed by 14 surgeons over 29 months; stereotactic and ultrasound guidance were used. During this time, 489 wire localizations were done, of which 159 used multiple wires. Two hundred eleven of these biopsies were done for malignant disease, 86 using multiple wires. After controlling for tumor node metastases stage, single and multiple wire placements were compared using endpoints of margin status, need for re-excision, and total volume of tissue removed. Neither margin status nor re-excision was related to the number of wires placed. However, the number of wires placed was significantly related to the total volume of tissue removed. Use of more than one localizing wire was associated with greater volume of tissue removal (measured in centimeters cubed) in benign disease (46 vs 25, P < 0.001), equivalent volumes in stage 0 disease (73 vs 67), less volume in stage 1 disease (113 vs 164), and less volume in stages 2 through 4 (158 vs 207, P = 0.03). Outcomes based on surgeon case volume during the study period demonstrated that low- (1-40), medium- (41-80), and high-volume (>80) surgeons did not differ in the type or stage of breast pathology treated. Surgeons with high case volumes were more likely to place multiple localizing wires (P < 0.001) and were more likely to do a breast-conserving procedure if re-excision was performed (P < 0.018). Surgeons with low case volumes were more likely to perform a re-excision (P < 0.025). Surgeon experience has a positive impact on quality outcome measures such as performance of a definitive procedure at the time of initial surgery and use of breast-conserving procedures at the time of re-excision. Multiple wire localization can be used to significantly reduce the volume of breast tissue removed in malignant disease without sacrificing margin status or increasing the need for future re-excision.

To describe gender difference in a total population of children with cerebral palsy (CP), related to subtype, gross and fine motor function, and to compare CP incidence trends in girls and boys. All 590 children with CP born in southern Sweden 1990-2005 were included. CP subtype was classified according to the Surveillance of Cerebral Palsy in Europe, gross motor function according to Gross Motor Function Classification System (GMFCS) and manual ability according to Manual Ability Classification System (MACS). Trends in CP incidence by birth year were analysed using Poisson regression modelling. There was a male predominance in all levels of GMFCS except level II, in all levels of MACS and in all CP subtypes except ataxic CP. There was no statistically significant difference between males and females regarding gross motor function or manual ability. The CP incidence trends in boys compared with girls did not change during the period 1990-2005. No equalization was detected in the incidence of CP between girls and boys during recent years in this total population. We could not confirm any consistent sex difference in motor function levels. Male sex is a risk factor for CP. ©2013 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

This study analysed the changes of excision margins in correlation with tumour thickness as recorded over the last three decades in Germany. The study also evaluated surgical management in different geographical regions and treatment options for metastasized melanoma. A total of 42 625 patients with invasive primary cutaneous melanoma, recorded by the German Central Malignant Melanoma Registry between 1976 and 2005 were included. Multiple linear regression analysis was used to investigate time trends of excision margins adjusted for tumour thickness. Excision margins of 5.0 cm were widely used in the late 1970s but since then have been replaced by smaller margins that are dependent on tumour thickness. In the case of primary melanoma, one-step surgery dominated until 1985 and was mostly replaced by two-step excisions since the early 1990s. In eastern Germany, one-step management remained common until the late 1990s. During the last three decades loco-regional metastases were predominantly treated by surgery (up to 80%), whereas systemic therapy decreased. The primary treatment of distant metastases has consistently been systemic chemotherapy. This descriptive retrospective study revealed a significant decrease in excision margins to a maximum of 2.00 cm. A significant trend towards two-step excisions in primary cutaneous melanoma was observed throughout Germany. Management of metastasized melanoma showed a tendency towards surgical procedures in limited disease and an ongoing trend to systemic treatment in advanced disease.

Systematic review and meta-analysis of the effect of equine assisted activities and therapies on gross motor outcome in children with cerebral palsy.

2013-01-01

To evaluate the literature on the efficacy of equine assisted activities and therapies (EAAT) on gross motor outcomes representing the ICF component of body functions and activity in children with cerebral palsy (CP). We conducted a systematic review and meta-analysis of randomized controlled trials and observational studies of hippotherapy (HPOT) and therapeutic horseback riding (TR) for children with spastic CP. Gross motor outcomes, assessed via muscle activity and muscle tone, gait, posture and Gross Motor Function Measures (GMFM) were evaluated. Five TR studies and nine HPOT studies were included. Our meta-analysis indicated that short-term HPOT (total riding time 8-10 min) significantly reduced asymmetrical activity of the hip adductor muscles. HPOT could improve postural control in children with spastic CP, GMFCS level < 5. However, the evidence did not show a statistically significant effect on GMFM after long-term HPOT or TR (total riding time, 8-22 h) in children with spastic CP. This systematic review found insufficient evidence to support the claim that long-term TR or HPOT provide a significant benefit to children with spastic CP. We found no statistically significant evidence of either therapeutic effect or maintenance effects on the gross motor activity status in CP children.

To describe the accuracy of the diagnosis of involved excision margins after loop electrosurgical excision procedure (LEEP) in a low-resource setting. Cross-sectional study of 176 LEEPs indicated for a cytological report of high-grade squamous intraepithelial lesion (HGSIL). A total of 72 HIV-positive and 104 HIV-negative women with cervical intraepithelial neoplasia (CIN) ≥ 2 on their LEEP histology report with involved excision margins were enrolled in the study. All patients underwent either a repeat LEEP or a hysterectomy. The specimens were evaluated for residual/recurrent CIN ≥ 2 or less. Persistent/recurrent CIN ≥ 2 was diagnosed in 139 (79.4%) instances and microinvasive squamous cell carcinoma in 6 (3.4%). Thirty (17.2%) showed CIN1. The persistence/recurrence rate was 72.2% and 88.5% in HIV-positive and HIV-negative women, respectively (χ2 = 7.5, p = 0.006). In > 80% the diagnosis of involved excision margins was confirmed, a positive predictive value of 82.4%. In the absence of more accurate follow-up methods such as HPV testing or co-testing with cytology, a correct diagnosis of margin status, especially when involved, is an important guide to further management and follow-up.

To investigate the accuracy of Medical Benefit Schedule (MBS) item numbers to identify treatments for basal cell carcinomas (BCC) and squamous cell carcinomas (SCC). We linked records from QSkin Study participants (n=37,103) to Medicare. We measured the proportion of Medicare claims for primary excision of BCC/SCC that had corresponding claims for histopathology services. In subsets of participants, we estimated the sensitivity and external concordance of MBS item numbers for identifying BCC/SCC diagnoses by comparing against 'gold-standard' histopathology reports. A total of 2,821 (7.6%) participants had 4,830 separate Medicare claims for BCC/SCC excision; almost all (97%) had contemporaneous Medicare claims for histopathology services. Among participants with BCC/SCC confirmed by histology reports, 76% had a corresponding Medicare claim for primary surgical excision of BCC/SCC. External concordance for Medicare claims for primary BCC/SCC excision was 68%, increasing to 97% when diagnoses for intra-epidermal carcinomas and keratoacanthomas were included. MBS item numbers for primary excision of BCC/SCC are reasonably reliable for determining incident cases of keratinocyte skin cancers, but may underestimate incidence by up to 24%. Medicare claims data may have utility in monitoring trends in conditions for which there is no mandatory reporting. © 2015 Public Health Association of Australia.

Low-grade central osteosarcoma of distal femur, resembling fibrous dysplasia

We report a case of a 32 year-old male, admitted for a lytic lesion of the distal femur. One month after the first X-ray, clinical and imaging deterioration was evident. Open biopsy revealed fibrous dysplasia. Three months later, the lytic lesion had spread to the whole distal third of the femur reaching the articular cartilage. The malignant clinical and imaging features necessitated excision of the lesion and reconstruction with a custom-made total knee arthroplasty. Intra-operatively, no obvious soft tissue infiltration was evident. Nevertheless, an excision of the distal 15.5 cm of the femur including 3.0 cm of the surrounding muscles was finally performed. The histological examination of the excised specimen revealed central low-grade osteosarcoma. Based on the morphological features of the excised tumor, allied to the clinical findings, the diagnosis of low-grade central osteosarcoma was finally made although characters of a fibrous dysplasia were apparent. Central low-grade osteosarcoma is a rare, well-differentiated sub-type of osteosarcoma, with clinical, imaging, and histological features similar to benign tumours. Thus, initial misdiagnosis is usual with the condition commonly mistaken for fibrous dysplasia. Central low-grade osteosarcoma is usually treated with surgery alone, with rare cases of distal metastases. However, regional recurrence is quite frequent after close margin excision. PMID:24147271

Early excision and grafting, an alternative approach to the surgical management of large body surface area levamisole-adulterated cocaine induced skin necrosis.

PubMed

Miner, Jason; Gruber, Paul; Perry, Travis L

2015-05-01

Levamisole-adulterated cocaine as a cause of retiform purpura progressing to full-thickness skin necrosis was first documented in 2003 and currently comprises over 200 reported cases. Whereas, its presentation, pathophysiology, and diagnostic workup have been reasonably well-defined, only one publication has significantly detailed its surgical management. For this reason there exists a relative absence of data in comparison to its reported incidence to suggest a preferred treatment strategy. In the case mentioned, treatment emphasized delayed surgical intervention while awaiting lesion demarcation and the monitoring of autoantibodies. At our institution we offer an alternative approach and present the case of a 34 year old female who presented with 49% TBSA, levamisole-induced skin necrosis managed with early surgical excision and skin grafting. The patient presented three days following cocaine exposure with painful, purpura involving the ears, nose, buttocks, and bilateral lower extremities which quickly progressed to areas of full-thickness necrosis. Lab analysis demonstrated elevated p-ANCA and c-ANCA, as well as leukopenia, decreased C4 complement, and urinalysis positive for levamisole, corroborating the diagnosis. Contrasting the most thoroughly documented case in which the patient underwent first surgical excision on hospital day 36 and underwent 18 total excisions, our patient underwent first excision on hospital day 10 and received only one primary excision prior to definitive autografting. To our knowledge, this is the largest surface area surgically treated that did not result in surgical amputation or autoamputation of limbs or appendages, respectively. We contend that early excision and grafting provides optimal surgical management of this syndrome while avoiding the morbidity seen with delayed intervention. Published by Elsevier Ltd.

Extralevator abdominoperineal excision results in superior oncologic outcome for advanced low rectal cancer. The exact definition of surgical resection planes is pivotal to achieving negative circumferential resection margins. This study aims to describe the surrounding anatomical structures that are at risk for inadvertent damage during extralevator abdominoperineal excision. Joint surgical and macroanatomical dissection was performed in a university laboratory of clinical anatomy. A stepwise dissection study was conducted according to the technique of extralevator abdominoperineal excision by abdominal and perineal approaches in 4 human cadaveric pelvises. Muscular, fascial, tendinous, and neural structures were carefully exposed and related to the corresponding surgical resection planes. In addition to the autonomic nerves to be identified and preserved during total mesorectal excision, further structures endangered during extralevator abdominoperineal excision can be clearly identified. Terminal pudendal nerve branches come close to the surgical resection plane at the outer surface of the puborectal sling. Likewise, the pelvic plexus and its neurovascular bundles embedded within the parietal pelvic fascia extend close to the apex of the prostate where the parietal pelvic fascia has to be divided. These neural structures converge in the region of the perineal body, an area that provides no "self-opening" planes for surgical dissection. Thus, the necessity to sharply detach the anorectal specimen anteriorly from the perineal body and the superficial transverse perineal muscle bears the risk of both inadvertent damage of the aforementioned anatomical structures and perforation of the specimen. The study focused primarily on the macroscopic topography relevant to the surgical procedure, so that previously published histologic examinations were not performed. The present anatomical dissection study highlights those anatomical landmarks that require clear identification for the successful achievement of both negative circumferential resection margins and preservation of urogenital functions during extralevator abdominoperineal excision.

Deep dermal burns require tangential excision of non-viable tissue and skin grafting to improve wound healing and burn-scar quality. Tangential excision is conventionally performed with a knife, but during the last decade hydrosurgery has become popular as a new tool for tangential excision. Hydrosurgery is generally thought to be a more precise and controlled manner of burn debridement leading to preservation of viable tissue and, therefore, better scar quality. Although scar quality is considered to be one of the most important outcomes in burn surgery today, no randomized controlled study has compared the effect of these two common treatment modalities with scar quality as a primary outcome. The aim of this study is, therefore, to compare long-term scar quality after hydrosurgical versus conventional tangential excision in deep dermal burns. A multicenter, randomized, intra-patient, controlled trial will be conducted in the Dutch burn centers of Rotterdam, Beverwijk, and Groningen. All patients with deep dermal burns that require excision and grafting are eligible. Exclusion criteria are: a burn wound < 50 cm 2 , total body surface area (TBSA) burned > 30%, full-thickness burns, chemical or electrical burns, infected wounds (clinical symptoms in combination with positive wound swabs), insufficient knowledge of the Dutch or English language, patients that are unlikely to comply with requirements of the study protocol and follow-up, and patients who are (temporarily) incompetent because of sedation and/or intubation. A total of 137 patients will be included. Comparable wound areas A and B will be appointed, randomized and either excised conventionally with a knife or with the hydrosurgery system. The primary outcome is scar quality measured by the observer score of the Patient and Observer Scar Assessment Scale (POSAS); a subjective scar-assessment instrument, consisting of two separate six-item scales (observer and patient) that are both scored on a 10-point rating scale. This study will contribute to the optimal surgical treatment of patients with deep dermal burn wounds. Dutch Trial Register, NTR6232 . Registered on 23 January 2017.

High-grade squamous intraepithelial lesion arising adjacent to vulvar lymphangioma circumscriptum: a tertiary institutional experience

PubMed Central

Bae, Go Eun; Yoon, Gun; Song, Yong Jung; Kim, Hyun-Soo

2016-01-01

Lymphangioma circumscriptum of the vulva occurs in patients who have undergone radical hysterectomy, lymph node dissection, or radiation therapy for management of advanced uterine cancer. Since vulvar lymphangioma circumscriptum typically presents as multiple, grossly verrucous vesicles of various sizes, it may be impossible to clinically distinguish vulvar lymphangioma circumscriptum from other vulvoperineal cutaneous diseases. In the present study, 16 (1.6%) out of the 1,024 vulvar biopsy or excision specimens were diagnosed as lymphangioma circumscriptum. In two (12.5%) out of the 16 cases, unusual histopathological findings were observed. Both patients had previously undergone radical hysterectomy with lymph node dissection and postoperative radiation therapy or concurrent chemoradiation therapy for advanced cervical cancer. Microscopic examination revealed high-grade squamous intraepithelial lesions, which were located immediately adjacent to the normal squamous epithelium covering the dilated subepithelial lymphatic vessels. Further, human papillomavirus genotyping confirmed that both patients were infected with high-risk human papillomavirus. High-grade squamous intraepithelial lesion cannot be grossly distinguished from vulvar lymphangioma circumscriptum because the multiple, verrucous vesicles that constitute the characteristic gross appearance of vulvar lymphangioma circumscriptum hinder its distinction. In this regard, our cases of high-grade squamous intraepithelial lesion, located adjacent to vulvar lymphangioma circumscriptum, support the notion that active surgical excision is necessary for the treatment of vulvar lymphangioma circumscriptum.

2018-04-01

Young children with autism spectrum disorder (ASD) often have gross motor delays that may accentuate problem daytime behavior and health-related quality of life (QoL). The objective of this study was to describe the degree of gross motor delays in young children with ASD and associations of gross motor delays with problem daytime behavior and QoL. The primary hypothesis was that Gross motor delays significantly modifies the associations between internalizing or externalizing problem daytime behavior and QoL. This study used a cross-sectional, retrospective analysis. Data from 3253 children who were 2 to 6 years old and who had ASD were obtained from the Autism Speaks Autism Treatment Network and analyzed using unadjusted and adjusted linear regression. Measures included the Vineland Adaptive Behavior Scales, 2nd edition, gross motor v-scale score (VABS-GM) (for Gross motor delays), the Child Behavior Checklist (CBCL) (for Problem daytime behavior), and the Pediatric Quality of Life Inventory (PedsQL) (for QoL). The mean VABS-GM was 12.12 (SD = 2.2), representing performance at or below the 16th percentile. After adjustment for covariates, the internalizing CBCL t score decreased with increasing VABS-GM (β = - 0.64 SE = 0.12). Total and subscale PedsQL scores increased with increasing VABS-GM (for total score: β = 1.79 SE = 0.17; for subscale score: β = 0.9-2.66 SE = 0.17-0.25). CBCL internalizing and externalizing t scores decreased with increasing PedsQL total score (β = - 0.39 SE = 0.01; β = - 0.36 SE = 0.01). The associations between CBCL internalizing or externalizing t scores and PedsQL were significantly modified by VABSGM (β = - 0.026 SE = 0.005]; β = - 0.019 SE = 0.007). The study lacked ethnic and socioeconomic diversity. Measures were collected via parent report without accompanying clinical assessment. Cross motor delay was independently associated with Problem daytime behavior and QoL in children with ASD. Gross motor delay modified the association between Problem daytime behavior and QoL. Children with ASD and co-occurring internalizing Problem daytime behavior had greater Gross motor delays than children without internalizing Problem daytime behavior; therefore, these children may be most appropriate for early physical therapist evaluation.

"The lobbying strategy is to keep excise as low as possible" - tobacco industry excise taxation policy in Ukraine

PubMed Central

2010-01-01

Background Tobacco taxes are one of the most effective ways to reduce tobacco use. Transnational tobacco companies (TTCs) claim they wish to develop and secure excise systems that benefit both governments and the profitability of the companies themselves. The objective of the paper is to use the case of Ukraine, with its inconsistent history of excise tax changes in 1992-2008, to explore tobacco industry taxation strategies and tactics, and their implications for governmental revenues. Methods Details of tobacco industry policy on tobacco taxation in Ukraine were obtained by searching tobacco industry internal documents and various published reports. Results Even before entering the market in Ukraine, TTCs had made efforts to change the excise system in the country. In 1993-1994, TTCs lobbied the Ukrainian Government, and succeeded in achieving a lowering in tobacco tax. This, however, did not produce revenue increase they promised the Government. In 1996-1998, Ukrainian authorities increased excise several times, ignoring the wishes of TTCs, caused significant growth in revenue. Due to TTCs lobbying activities in 1999-2007 the tax increases were very moderate and it resulted in increased tobacco consumption in Ukraine. In 2008, despite the TTCs position, excise rates were increased twice and it was very beneficial for revenues. Conclusions The Framework Convention on Tobacco Control includes provisions both on tobacco taxation policy and on protection of public health policy from vested interests of tobacco industry. This paper provides arguments why tobacco taxation policy should also be protected from vested interests of tobacco industry. TTCs taxation strategy appears to be consistent: keep excise as low as possible. Apparent conflicts between TTCs concerning tax structures often hide their real aim to change tax structures for competing interests without increasing total tax incidence. Governments, that aim to reduce levels of tobacco use, should not allow tobacco companies to influence the development and implementation of tobacco taxation policy. PMID:20807434

The spectrum of skin biopsies and excisions in a pediatric skin center.

Little is known about the spectrum of pediatric skin disorders requiring biopsy/excision, their indication, impact on further management, and the accuracy of clinical diagnosis. We aimed to address these questions in the patient population seen at our Swiss University referral center for Pediatric Dermatology and Plastic Surgery. All skin biopsies/excisions performed in patients aged ≤ 16 years over a period of 2 years were retrospectively analyzed. A total of 506 samples were included. The majority of biopsies/excisions (n = 413, 82%) was performed for tumors, cysts, and hamartomas and 18% for other skin conditions. Malignant tumors were found in 12 samples (2%) from four patients. In 121 (24%) patients, the histopathology had an important impact on patient management. In 80 (16%) cases, the pathology did not match with the clinical diagnosis. In 382 (75%) cases, excision was the treatment of choice. Of these, the indication for surgery was based on patient's request in 181 (47%) cases. Surgical interventions for pediatric skin disorders are performed for diagnostic and therapeutic reasons. In this cohort, histopathology was essential for treatment in one quarter of cases. Skin tumors, cysts, and hamartomas often require excision during childhood, with families' request and esthetic considerations playing an important role. What is Known: • The spectrum of pediatric skin conditions has been studied in outpatient, inpatient, and emergency settings. • In contrast, no data exist on the spectrum of pediatric skin disorders undergoing biopsy/excision specifically. What is New: • We analyze biopsies/excisions in children, focusing on diagnosis, indication, and impact on patient management. • Surgical interventions for skin disorders in children are often performed for tumors and hamartomas with esthetic considerations playing a relevant role. If used for diagnostic purposes, they are often performed to confirm or rule out severe skin disease.

Rectal cancer is an important health problem, due to the increasing number of new cases and the quality of life issues brought forth by surgical treatment in these patients. The aim of the study was to analyse the results of robotic surgery in the treatment of lower and middle rectal cancer,locations in which TME is performed. Patients diagnosed with and operated on for rectal cancer by the means of robotic surgery between 2008-2012 at the Fundeni Clinical Institute were retrospectively analysed. A number of 117 patients with rectal cancer were operated on by robotic surgery, of which 79 (67.52%) were submitted to total mesorectal excision (TME). The most frequently performed surgery was low anterior resection, followed by rectal amputation through abdominoperineal approach.Anastomosis fistula was observed in 9 (11.39%) patients. Local recurrence was encountered in 2 (2.53%) of the robotically performed surgeries. 1. Robotically assisted total mesorectal excision is feasible, safe and can be performed with a small number of complications and a low local recurrence rate; 2. The main advantages are oncological safety and quality of life; 3.Conversion to open surgery is rarely encountered; 4. Protection loop ileostomy existence allows avoiding reintervention in case anastomotic fistula occurs in patients with low anterior resection. 5. Robotic surgery may become gold standard in the surgical treatment of rectal cancer. Celsius.

Is excision biopsy of fibroadenomas based solely on size criteria warranted?

Fibroadenomas (FA) are the most common benign tumor in the female breast. Most are managed conservatively provided there is clinical, radiologic, and pathologic concordance. However, surgical excision is typically recommended for cellular fibroepithelial lesions or those lesions with clinical, radiologic, or pathologic features concerning for phyllodes tumor (PT). Some studies have suggested surgical excision in all FA >30 mm to reduce core needle biopsy (CNB) sampling errors. The aim of our study was to evaluate, in the absence of any other concerning clinicopathologic features, whether surgical excision of FA was warranted based on size criteria alone. Cork University Hospital is a large academic center in Southern Ireland. Its breast cancer center provides both a screening and symptomatic service and diagnoses approximately 600 cancers per year. The breast histopathological data base was reviewed for all CNBs from January 1, 2010, to June 30, 2015, with a diagnosis of FA that went on to have excision at our institution. We excluded all cellular fibroepithelial lesions and those cases with co-existent lobular neoplasia, ductal carcinoma in situ, invasive carcinoma, atypical ductal hyperplasia, or lesions which would require excision in their own right. Cases in which the radiologic targeted mass was discordant with a diagnosis of FA were also excluded. Patient demographics and preoperative radiologic size and the radiologic target were recorded in each case. All radiology was reviewed by a breast radiologist prior to inclusion in the study, and there was histologic radiologic concordance with a diagnosis of FA in all cases. A total of 12,109 consecutive radiologically guided CNB were performed January 2010-June 2015; 3438 with a diagnosis of FA were identified of which 290 cases went on to have surgical excision. Of those 290 cases; 98.28% (n = 285) were confirmed as FA on excision. The remaining 1.72% (n = 5) had atypical features-FA with LCIS (n = 1), benign PT (n = 3), and invasive ductal carcinoma (n = 1). Our study suggests that, excision based solely on size is not warranted in clinical and radiologically concordant cases with a diagnosis of FA on CNB. © 2018 Wiley Periodicals, Inc.

To present the author's experience with various treatment methods of granulomatous lobular mastitis (GLM) and to determine effective treatment methods of GLM. Fifty patients who were diagnosed with GLM were classified into five groups based on the initial treatment methods they underwent, which included observation (n = 8), antibiotics (n = 3), steroid (n = 13), drainage (n = 14), and surgical excision (n = 12). The treatment processes in each group were examined and their clinical characteristics, treatment processes, and results were analyzed respectively. Success rates with each initial treatment were observation, 87.5%; antibiotics, 33.3%; steroids, 30.8%; drainage, 28.6%; and surgical excision, 91.7%. In most cases of observation, the lesions were small and the symptoms were mild. A total of 23 patients underwent surgical excision during treatment. Surgical excision showed particularly fast recovery, high success rate (90.3%) and low recurrence rate (8.7%). The clinical course of GLM is complex and the outcome of each treatment type are variable. Surgery may play an important role when a lesion is determined to be mass-forming or appears localized as an abscess pocket during breast examination or imaging study.

Increasing excise taxes in the presence of an illegal cigarette market: the 2011 Brazil tobacco tax reform.

Iglesias, Roberto Magno

2016-10-01

The Brazilian cigarette excise tax reform of 2011 increased tax rates significantly in the presence of a high proportion of illegal and cheap cigarettes contributing to total consumption. Prior to 2011, tobacco tax policy in Brazil had reduced excise tax share on consumer prices, for fear of smuggling. This report examines two hypotheses explaining why tax authorities changed direction. The first is related to lack of concern regarding smuggling in tobacco industry pricing behavior before 2011 (rather than reducing prices following tax reduction, legal companies increased net of tax prices above inflation and key costs). The second hypothesis regards inconsistent industry assessments of the size of the illicit market, which ultimately undermined the credibility of the industry with tax authorities. The author concludes that the 2011 reform was designed to revert the weakness of previous policies, and did indeed succeed. The post-2011 experience in Brazil indicates that increased cigarette excise taxes can increase government revenues and reduce smoking prevalence and consumption despite widespread smuggling of tobacco products.

Pythons are unique amongst snakes in having different pressures in the aortas and pulmonary arteries because of intraventricular pressure separation. In this study, we investigate whether this correlates with different blood vessel strength in the ball python Python regius. We excised segments from the left, right, and dorsal aortas, and from the two pulmonary arteries. These were subjected to tensile testing. We show that the aortic vessel wall is significantly stronger than the pulmonary artery wall in P. regius. Gross morphological characteristics (vessel wall thickness and correlated absolute amount of collagen content) are likely the most influential factors. Collagen fiber thickness and orientation are likely to have an effect, though the effect of collagen fiber type and cross-links between fibers will need further study. © 2015 Wiley Periodicals, Inc.

Background Early detection of melanoma is the best way to improve prognosis. Digital follow up (DFU) programs of high-risk populations could be an efficient strategy for detecting early melanomas with low morbidity. Objective to report the added value of the use of the “two-step method” (digital total-body photography and digital dermoscopy) Methods Analysis of the surveillance of 618 high-risk melanoma patients included in our DFU-program from 1999 to 2008. Results A total of 11396 lesions were monitored (mean 18.44 per patient) during a median follow-up of 96 months (median 10 visits per patient). 1152 lesions, 1.86 per patient, were excised. Almost 70% (798) were lesions previously registered at least twice, while 356 (30%) were detected and removed in the same visit. During follow-up, 98 melanomas (8.5% of excised lesions) were diagnosed in 78 patients (12.6%). 53 melanomas were in situ (53.3%), while invasive (45) showed a Breslow index of less than 1 mm (median 0.5 mm) and none was ulcerated. Limitations Since there are no control groups we cannot convey if the combined use of total-body photography and digital dermoscopy is more beneficial than these techniques used separately. Conclusion DFU with Total-Body Photography and Dermoscopy in a selected high-risk population demonstrated the early detection of melanomas with a low rate of excisions. Long-term follow-up is required to allow the detection of slow growing melanomas. Based on our 10-year experience, melanomas can be diagnosed at any time, suggesting that in high-risk population, DFU should be maintained with time. PMID:21683472

Transanal Total Mesorectal Excision: A Novel Approach to Rectal Surgery

PubMed Central

Suwanabol, Pasithorn A.; Maykel, Justin A.

2017-01-01

Less invasive approaches continue to be explored and refined for diseases of the colon and rectum. The current gold standard for the surgical treatment of rectal cancer, total mesorectal excision (TME), is a technically precise yet demanding procedure with outcomes measured by both oncologic and functional outcomes (including bowel, urinary, and sexual). To date, the minimally invasive approach to rectal cancer has not yet been perfected, leaving ample opportunity for rectal surgeons to innovate. Transanal TME has recently emerged as a safe and effective technique for both benign and malignant diseases of the rectum. While widespread acceptance of this surgical approach remains tempered at this time due to lack of long-term oncologic outcome data, short-term outcomes are promising and there is great excitement surrounding the promise of this technique.

Groundwater is the most valuable resource in arid regions, and recognizing radiological criteria among other water quality parameters is essential for sustainable use. In the investigation presented here, gross-α and gross-β were measured in groundwater samples collected in the south-eastern Arabian Peninsula, 67 wells in Unite Arab Emirates (UAE), as well as two wells and one spring in Oman. The results show a wide gross-α and gross-β activities range in the groundwater samples that vary at 0.01∼19.5 Bq/l and 0.13∼6.6 Bq/l, respectively. The data show gross-β and gross-α values below the WHO permissible limits for drinking water in the majority of the investigated samples except those in region 4 (Jabel Hafit and surroundings). No correlation between groundwater pH and the gross-α and gross-β, while high temperatures probably enhance leaching of radionuclides from the aquifer body and thereby increase the radioactivity in the groundwater. This conclusion is also supported by the positive correlation between radioactivity and amount of total dissolved solid. Particular water purification technology and environmental impact assessments are essential for sustainable and secure use of the groundwater in regions that show radioactivity values far above the WHO permissible limit for drinking water.

OBJECTIVE To compare fees for biopsy, treatment procedure, repair, and 2-month follow-up for nonmelanoma skin cancer (NMSC) treatments: electrodesiccation and curettage (ED&C), excision, and Mohs micrographic surgery (MMS). METHODS A cost comparison of 936 primary NMSCs diagnosed in 1999/2000 at a University affiliated dermatology practice. Clinical data was from medical record review. 2007 Medicare Fee Schedule costs determined fees for surgical care. Pearson chi-square tests, t-tests and analysis of variance compared fee differences. Linear regression determined independent effects of tumor and treatment characteristics on fees. RESULTS Mean fees/lesion were $463 for ED&C, $1,222 for excision, and $2,085 for MMS (p < .001). For all treatments, primary procedure costs were highest (38%, 45%, and 41%). Total repair fees were higher with MMS ($735) vs excisions ($197). Fees were higher for head and neck tumors (p < .001), H-zone tumors (p < .001), and tumors smaller than 10 mm in diameter (p = .04). Regression models predicted that the treatment fees would be $2,109 for MMS and $1,252 for excision (p < .001). Tumor size greater than 10 mm in diameter (added $128), tumors on the head and neck (added $966), and MMS (added $857 vs excision) were independently related to higher fees (p < .001). CONCLUSION Even after adjusting for risk factors, MMS has higher fees than excision for primary NMSC. Repairs accounted for the majority of this difference. These fee comparisons provide a basis for comparative effectiveness studies of treatments for this common cancer. PMID:22145798

Chemical burns are rare but often lead to deep cutaneous lesions. Alkali agents have a deep and long lasting penetrating power, causing burns that evolve over several days. The local treatment for these patients is excision of the wound and split thickness skin graft. Early excision and immediate skin grafting of alkali burns are more likely to be complicated by graft failure and delayed wound healing. We propose a two-step method that delays skin grafting until two-three days after burn wound excision. Our population included 25 controls and 16 cases. Men were predominant with a mean age of 41.9 years. In 78% of cases, burns were located on the lower limbs. The mean delay between the burn and excision was 16.5 days. In cases, the skin graft was performed at a mean of 11.3 days after the initial excision. We did not unveil any significant difference between both groups for the total skin surface affected, topography of the burns and the causal agent. Wound healing was significantly shorter in cases vs controls (37.5 days vs 50.3 days; P<0.025). Furthermore, we observed a decreased number of graft failures in cases vs controls (13.3% vs 46.7%; P=0.059). Our study shows the relevance of a two-step surgical strategy in patients with alkali chemical burns. Early excision followed by interval skin grafting is associated with quicker wound healing and decreased rate of graft failure. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

Perkins, Stephanie M.; Rubin, Joshua B.; Leonard, Jeffrey R.

2011-07-15

Purpose: Current treatment recommendations for pediatric glioblastoma include surgery, chemotherapy, and radiation therapy. However, even with this multispecialty approach, overall survival remains poor. To assess outcome and evaluate treatment-related prognostic factors, we retrospectively reviewed the experience at our institution. Methods and Materials: Twenty-four glioblastoma patients under the age of 21 were treated with radiation therapy with curative intent at Washington University, St. Louis, from 1970 to 2008. Patients underwent gross total resection, subtotal resection or biopsy alone. Fourteen (58%) of the patients received chemotherapy. All patients received radiation therapy. Radiation consisted of whole-brain radiation therapy in 7 (29%) patients withmore » a median dose of 50.4 Gy. Seventeen (71%) patients received three-dimensional conformal radiation therapy with a median dose of 54 Gy. Results: Median follow-up was 12.5 months from diagnosis. One and 2-year overall survival rates were 57% and 32%, respectively. Median overall survival was 13.5 months. There were no differences in overall survival based on patients' age, race, gender, tumor location, radiation volume, radiation dose, or the use of chemotherapy. There was a significant improvement in overall survival for patients in whom gross total resection was achieved (p = 0.023). Three patients were alive 5 years after gross total resection, and 2 patients were alive at 10 and 24 years after diagnosis. Conclusions: Survival for children with glioblastoma remains poor. Data from this and other studies demonstrate the importance of achieving a gross total resection. Continued investigation into new treatment options is needed in an attempt to improve outcome for these patients.« less

2016-09-01

Necrotizing fasciitis is a serious soft-tissue infection associated with sepsis and tissue destruction. Surgical management usually requires extensive débridement of necrotic fascia and overlying skin, with significant aesthetic and functional consequences. The authors review the outcome of all recent cases of necrotizing fasciitis treated with skin-sparing débridement at their institution. The authors conducted a retrospective review of all of their cases of necrotizing fasciitis treated with skin-sparing débridement. Medical records were evaluated with a standard form gathering relevant demographic and clinical data. All cases were confirmed as necrotizing fasciitis histologically. Ten patients were admitted with a diagnosis of necrotizing fasciitis. The median age of the patients was 4.9 years (range, 1.7 to 15.1 years). The majority of initial lesions were caused by chickenpox, mostly on the trunk. Interval from admission to surgery was 6 hours (range, 1 to 27.5 hours), with a median hospital stay of 11 days (range, 5 to 43 days). Median fasciectomy was 2.5 percent (range, 1 to 15 percent) of total body surface area, with a median skin excision of 0.25 percent of total body surface area (range, 0.1 to 3 percent). All patients received intravenous amoxicillin/clavulanic acid plus clindamycin. Delayed direct closure was possible for all patients. Median follow-up was 17 months (range, 3 to 79 months). There was no death in this series. This surgical management restricts skin excision to the area of definite skin necrosis, limiting skin excision to one-tenth of excised fascia, with long-term favorable cosmetic and functional results.

Inability to visualize indocyanine green fluorescence images in the surgical field limits the application of current near-infrared fluorescence imaging (NIR) systems for real-time navigation during sentinel lymph node (SLN) biopsy in breast cancer patients. The aim of this study was to evaluate the usefulness of the Medical Imaging Projection System (MIPS), which uses active projection mapping, for SLN biopsy. A total of 56 patients (59 procedures) underwent SLN biopsy using the MIPS between March 2016 and November 2017. After SLN biopsy using the MIPS, residual SLNs were removed using a conventional NIR camera and/or radioisotope method. The primary endpoint of this study was identification rate of SLNs using the MIPS. In all procedures, at least one SLN was detected by the MIPS, giving an SLN identification rate of 100% [95% confidence interval (CI) 94-100%]. SLN biopsy was successfully performed without operating lights in all procedures. In total, 3 positive SLNs were excised using MIPS, but were not included in the additional SLNs excised by other methods. The median number of SLNs excised using the MIPS was 3 (range 1-7). Of procedures performed after preoperative systemic therapy, the median number of SLNs excised using the MIPS was 3 (range 2-6). The MIPS is effective in detecting SLNs in patients with breast cancer, providing continuous and accurate projection of fluorescence signals in the surgical field, without need for operating lights, and could be useful in real-time navigation surgery for SLN biopsy.

Here, we present the clinical presentation and surgical outcomes of women with symptomatic urethral prolapse presenting to our institution over 20 years, and seek to provide treatment recommendations for management of symptomatic urethral prolapse and caruncle. A retrospective review of medical records from female patients who underwent surgery for symptomatic urethral prolapse from June 1995 to August 2015 was performed. Surgical technique consisted of a four-quadrant excisional approach for repair of urethral prolapse. A total of 26 patients were identified with a mean age of 38.8 years (range 3-81). The most common presentations were vaginal bleeding, hematuria, pain, and dysuria. All patients underwent surgical excision of urethral prolapse via a standard approach. Follow-up data was available in 24 patients. Six patients experienced temporary postoperative bleeding, and one patient required placement of a Foley catheter for tamponade. One patient experienced temporary postoperative urinary retention requiring Foley catheter placement. Three patients had visible recurrence of urethral prolapse, for which one later underwent re-excision. Surgical excision of urethral prolapse is a reasonable treatment option in patients who have tried conservative management without relief, as well as in those who present with severe symptoms. Possible complications following excision include postoperative bleeding and recurrence, and patients must be counseled accordingly. In this work, we propose a treatment algorithm for symptomatic urethral prolapse. © 2017 Wiley Periodicals, Inc.

The concentrations of gross alpha radioactivity minus uranium equaled or exceeded 15 picoCuries/L (pCi/L) in five of 14 wells sampled. The concentration of radium-226 plus radium-228 exceeded the primary water quality standard of 5 pCi/L in one well. The concentration of uranium exceeded a recommended limit of 0.035 mg/L in two wells. Perennial grass and sediment samples had low concentrations of radionuclides. The concentration of trace elements in the sediment samples was not unusual. Water quality of surface water in the Puerco River at Chambers varied as a function of the suspended sediment concentration. Concentrations of total gross alpha radiation fluctuated from 12 to 11,200 pCi/L. Concentrations of total gross beta radiation fluctuated from 45 to 4,500 pCi/L. (Author 's abstract)

Identification of a novel AluSx-mediated deletion of exon 3 in the SBDS gene in a patient with Shwachman-Diamond syndrome.

Shwachman-Diamond syndrome (SDS) is caused by mutations in the SBDS gene, most of which are the result of gene conversion events involving its highly homologous pseudogene SBDSP. Here we describe the molecular characterization of the first documented gross deletion in the SBDS gene, in a 4-year-old Portuguese girl with SDS. The clinical diagnosis was based on the presence of hematological symptoms (severe anemia and cyclic neutropenia), pancreatic exocrine insufficiency and skeletal abnormalities. Routine molecular screening revealed heterozygosity for the common splicing mutation c.258+2T>C, and a further step-wise approach led to the detection of a large deletion encompassing exon 3, the endpoints of which were subsequently delineated at the gDNA level. This novel mutation (c.258+374_459+250del), predictably giving rise to an internally deleted polypeptide (p.Ile87_Gln153del), appears to have arisen from an excision event mediated by AluSx elements which are present in introns 2 and 3. Our case illustrates the importance of including gross deletion screening in the SDS diagnostic setting, especially in cases where only one deleterious mutation is detected by routine screening methods. In particular, deletional rearrangements involving exon 3 should be considered, since Alu sequences are known to be an important cause of recurrent mutations.

To investigate the relationship between obesity and gross motor development in children who are developing typically and determine whether body mass index (BMI) predicts difficulty in gross motor skills. BMIs were calculated and gross motor skills examined in 50 children who were healthy aged 3 to 5 years using the Peabody Developmental Motor Scales, 2nd edition (PDMS-2). Pearson chi-square statistic and stepwise linear hierarchical regression were used for analysis. A total of 24% of the children were overweight/obese, whereas 76% were found not to be overweight/obese. Fifty-eight percent of the overweight/obese group scored below average on the PDMS-2 compared to 15% of the nonoverweight group. Association between BMI and gross motor quotients was identified with significance of less than 0.002. Regression results were nonsignificant with all 50 subjects, yet showed significance (P = 0.018) when an outlier was excluded. Children aged 3 to 5 years with high BMIs may have difficulty with their gross motor skills. Further research is needed.

Background. Being predictive of the entire nodal bed, sentinel lymph node biopsy (SLNB) is invaluable in the surgical management of melanoma. Although the concept is simple, sentinel lymph node (SLN) identification and removal can be technically challenging. Methods. A total of 102 consecutive patients have undergone SLNB in the Division of Plastic and Reconstructive Surgery of Soroka University Medical Center from 2009 to 2012. Patients have undergone SLNB using a radioactive tracer and blue stain in order to identify the SLN. Although SLNB usually precedes the wide excision of melanoma, primary lesions in close proximity (<10 cm) to the lymph basin require wide excision before beginning the SLN quest. Results. All pathology reports confirmed the excision of lymph nodes. Conclusions. When treating MM in close proximity to the lymph basin, changing the sequence of the SLNB procedure seems to increase the efficacy of the method. PMID:24660067

Improvement in any human activity is preconditioned by inspection of results and providing feedback used for modification of the processes applied. Comparison of experts experience in the given field is another indispensable part leading to optimisation and improvement of processes, and optimally to implementation of standards. For the purpose of objective comparison and assessment of the processes, it is always necessary to describe the processes in a parametric way, to obtain representative data, to assess the achieved results, and to provide unquestionable and data-driven feedback based on such analysis. This may lead to a consensus on the definition of standards in the given area of health care. Total mesorectal excision (TME) is a standard procedure of rectal cancer (C20) surgical treatment. However, the quality of performed procedures varies in different health care facilities, which is given, among others, by internal processes and surgeons experience. Assessment of surgical treatment results is therefore of key importance. A pathologist who assesses the resected tissue can provide valuable feedback in this respect. An information system for the parametric assessment of TME performance is described in our article, including technical background in the form of a multicentre clinical registry and the structure of observed parameters. We consider the proposed system of TME parametric assessment as significant for improvement of TME performance, aimed at reducing local recurrences and at improving the overall prognosis of patients. rectal cancer total mesorectal excision parametric data clinical registries TME registry.

Intramedullary spinal cord teratomas are rare entities in infants. Management of these lesions is primarily surgical, with outcome dependent on rapid surgical decompression and complete gross-total tumor resection. The lesions are typically of the mature type, with immature teratomas displaying unique pathological features. The authors report a case of an extensive intramedullary immature teratoma in an infant with resolution of quadriplegia following gross-total radical resection. At the 1-year follow-up, there was radiographic evidence of tumor, and surgical reexploration yielded portions of immature teratoma and extensive gliosis.

To describe the gross motor development of infants who had undergone cardiac surgery in the neonatal or early infant period. Gross motor performance was assessed when infants were 4, 8, 12, and 16 months of age with the Alberta Infant Motor Scale. This scale is a discriminative gross motor outcome measure that may be used to assess infants from birth to independent walking. Infants were videotaped during the assessment and were later evaluated by a senior paediatric physiotherapist who was blinded to each infant's medical history, including previous clinical assessments. Demographic, diagnostic, surgical, critical care, and medical variables were considered with respect to gross motor outcomes. A total of 50 infants who underwent elective or emergency cardiac surgery at less than or up to 8 weeks of age, between July 2006 and January 2008, were recruited to this study and were assessed at 4 months of age. Approximately, 92%, 84%, and 94% of study participants returned for assessment at 8, 12, and 16 months of age, respectively. Study participants had delayed gross motor development across all study time points; 62% of study participants did not have typical gross motor development during the first year of life. Hospital length of stay was associated with gross motor outcome across infancy. Active gross motor surveillance of all infants undergoing early cardiac surgery is recommended. Further studies of larger congenital heart disease samples are required, as are longitudinal studies that determine the significance of these findings at school age and beyond.

Patients with incomplete surgical resection of medulloblastoma are controversially regarded as having a marker of high-risk disease, which leads to patients undergoing aggressive surgical resections, so-called second-look surgeries, and intensified chemoradiotherapy. All previous studies assessing the clinical importance of extent of resection have not accounted for molecular subgroup. We analysed the prognostic value of extent of resection in a subgroup-specific manner. We retrospectively identified patients who had a histological diagnosis of medulloblastoma and complete data about extent of resection and survival from centres participating in the Medulloblastoma Advanced Genomics International Consortium. We collected from resections done between April, 1997, and February, 2013, at 35 international institutions. We established medulloblastoma subgroup affiliation by gene expression profiling on frozen or formalin-fixed paraffin-embedded tissues. We classified extent of resection on the basis of postoperative imaging as gross total resection (no residual tumour), near-total resection (<1·5 cm(2) tumour remaining), or sub-total resection (≥1·5 cm(2) tumour remaining). We did multivariable analyses of overall survival and progression-free survival using the variables molecular subgroup (WNT, SHH, group 4, and group 3), age (<3 vs ≥3 years old), metastatic status (metastases vs no metastases), geographical location of therapy (North America/Australia vs rest of the world), receipt of chemotherapy (yes vs no) and receipt of craniospinal irradiation (<30 Gy or >30 Gy vs no craniospinal irradiation). The primary analysis outcome was the effect of extent of resection by molecular subgroup and the effects of other clinical variables on overall and progression-free survival. We included 787 patients with medulloblastoma (86 with WNT tumours, 242 with SHH tumours, 163 with group 3 tumours, and 296 with group 4 tumours) in our multivariable Cox models of progression-free and overall survival. We found that the prognostic benefit of increased extent of resection for patients with medulloblastoma is attenuated after molecular subgroup affiliation is taken into account. We identified a progression-free survival benefit for gross total resection over sub-total resection (hazard ratio [HR] 1·45, 95% CI 1·07-1·96, p=0·16) but no overall survival benefit (HR 1·23, 0·87-1·72, p=0·24). We saw no progression-free survival or overall survival benefit for gross total resection compared with near-total resection (HR 1·05, 0·71-1·53, p=0·8158 for progression-free survival and HR 1·14, 0·75-1·72, p=0·55 for overall survival). No significant survival benefit existed for greater extent of resection for patients with WNT, SHH, or group 3 tumours (HR 1·03, 0·67-1·58, p=0·89 for sub-total resection vs gross total resection). For patients with group 4 tumours, gross total resection conferred a benefit to progression-free survival compared with sub-total resection (HR 1·97, 1·22-3·17, p=0·0056), especially for those with metastatic disease (HR 2·22, 1·00-4·93, p=0·050). However, gross total resection had no effect on overall survival compared with sub-total resection in patients with group 4 tumours (HR 1·67, 0·93-2·99, p=0·084). The prognostic benefit of increased extent of resection for patients with medulloblastoma is attenuated after molecular subgroup affiliation is taken into account. Although maximum safe surgical resection should remain the standard of care, surgical removal of small residual portions of medulloblastoma is not recommended when the likelihood of neurological morbidity is high because there is no definitive benefit to gross total resection compared with near-total resection.

Xeroderma pigmentosum is an autosomal recessive disease, characterized by vulnerability of the skin to solar radiation. Increase in sunlight-induced cancer is a direct consequence of an increase in mutated cells of the skin of patients with xeroderma pigmentosum. There is no specific technique for facial resurfacing in patients with xeroderma pigmentosum. In this article, a patient with xeroderma pigmentosum with multiple malignant melanomas on her face and radical excision of total facial skin followed by facial resurfacing with monoblock full-thickness skin graft from the abdomen is presented.

Purpose To present the author's experience with various treatment methods of granulomatous lobular mastitis (GLM) and to determine effective treatment methods of GLM. Methods Fifty patients who were diagnosed with GLM were classified into five groups based on the initial treatment methods they underwent, which included observation (n = 8), antibiotics (n = 3), steroid (n = 13), drainage (n = 14), and surgical excision (n = 12). The treatment processes in each group were examined and their clinical characteristics, treatment processes, and results were analyzed respectively. Results Success rates with each initial treatment were observation, 87.5%; antibiotics, 33.3%; steroids, 30.8%; drainage, 28.6%; and surgical excision, 91.7%. In most cases of observation, the lesions were small and the symptoms were mild. A total of 23 patients underwent surgical excision during treatment. Surgical excision showed particularly fast recovery, high success rate (90.3%) and low recurrence rate (8.7%). Conclusion The clinical course of GLM is complex and the outcome of each treatment type are variable. Surgery may play an important role when a lesion is determined to be mass-forming or appears localized as an abscess pocket during breast examination or imaging study. PMID:23833753

2018-02-01

The purpose of this study was to assess the long-term outcomes of radioscapholunate fusion, with and without distal pole of scaphoid excision and excision of the triquetrum. These compromised three operative groups. Seventeen patients were identified with a minimum of 10 years follow-up, with a mean of 15 years (range 10-19). Fifteen of the 17 patients were satisfied with their outcome. Two were converted to total wrist fusion. The mean outcomes scores were; pain visual analogue scale score 2.1/10, Quick Disabilities of the Arm, Shoulder, and Hand 29 and Modified Mayo Wrist score 60. Patients with excision of the triquetrum had a mean radial-ulnar arc increase of 10° compared with the other two groups, but this was not statistically significant. The mean space for the scaphocapitate joint was 1.7 mm and lunocapitate joint was 1.3 mm at latest follow-up. Close adherence to the indications and surgical technique provided a sustainable good clinical outcome. Patients who obtained a good result at 2 years were likely to achieve a good long-term outcome.

Six patients with giant cell tumor of the spine had surgery between 1981 and 1995. Three lesions were located in the scrum, two lesions were in the thoracic spine, and one lesion was in the lumbar spine. Preoperatively, all patients had local pain and neurologic symptoms. Two patients had cement implanted after curettage or intralesional excision of the sacral tumor; one patient had a local relapse. After the second curettage and cement implantation, the tumor was controlled. One patient with a sacral lesion had marginal excision and spondylodesis; no relapse developed. Two patients with thoracic lesions had planned marginal excision and spondylodesis; the margins finally became intralesional, but no relapse developed. One patient with a lumbar lesion had incomplete removal of the tumor and received postoperative irradiation. At the final followup (median, 69 months), five of six patients were disease-free and one patient died of disease progression. Two of the five surviving patients had pain after standing or neurologic problems. Although some contamination occurred, planning a marginal excision of the lesion seems beneficial for vertebral lesions above the sacrum. Total sacrectomy of a sacral lesion seems to be too invasive when cement implantation can control the lesion.

Advanced pelvic cancers involving the lateral pelvic compartment, and particularly the iliac vasculature, are difficult to manage. Common or external iliac vessel involvement has traditionally been considered a contraindication for curative surgery. The purpose of this study was to investigate pathological and surgical outcomes, particularly postoperative morbidity of pelvic exenteration with en bloc major iliac vascular excision and reconstruction. This study was a case series. The study was conducted at a quaternary referral center for pelvic exenteration in Sydney. Patients included those undergoing en bloc iliac vessel excision as part of their pelvic exenteration for a locally advanced pelvic malignancy. Over the study period, 336 patients underwent pelvic exenteration. Twenty-one patients (6.3%) underwent en bloc vascular excision of 29 vessels for tumor involvement. Twenty-four vessels required reconstruction. The primary outcomes were postoperative complications and pathologic outcomes. Survival rates were estimated using the Kaplan-Meier technique. Operating time for patients who underwent vascular excision and reconstruction was longer, but this did not reach significance (631 vs 531 minutes; p = 0.052). Mean blood loss was significantly higher in the vascular excision and reconstruction group (6.8 vs 3.4 L; p < 0.001). Patients who required en bloc vascular excision were less likely to have R0 margins compared with patients who did not (38% vs 78%; p < 0.001). There was no intraoperative or 30-day mortality. Overall graft patency and limb loss at 1 year were 96% and 0%. A total of 52% of patients had at least 1 vascular related complication. Median overall and disease-free survival times were 34 and 26 months. This study is limited by a relatively small number of heterogeneous patients. En bloc vascular resection and reconstruction for contiguous tumor involvement is feasible and safe in selected patients. Advanced pelvic tumors involving iliac vessels should not be precluded from curative surgery in specialized institutions.

The biological behavior and the optimal management of benign breast lesions with uncertain malignant potential, the so-called B3 lesions, found in breast needle core biopsies is still under debate. We addressed this study to compare histologic findings in B3 needle core biopsies with final excision specimens to determine associated rates of malignancy. Consecutive needle core biopsies were performed in a 3-year period (January 1, 2006-December 31, 2008). Biopsies were image-guided (31 by ultrasound, 85 stereotactic vacuum-assisted, 6 unknown) for evaluation of breast abnormalities. We reviewed 122 needle core biopsies with B3 lesions of 91 symptomatic patients and 31 screen-detected women and compared the B3 histologic subtypes with the final excision histology. A total of 1845 needle core biopsies were performed and B3 lesions comprised 6.6% of all B categories. The most common histologic subtype in biopsies was flat epithelia atypia in 35.2%, followed by papillary lesions in 21% and atypical ductal hyperplasia in 20%. Reports on excision specimens were available in 66% (81 patients). Final excision histology was benign in 73 (90.2%) and malignant in 8 (9.8%) patients (2 invasive cancer, 6 ductal carcinoma in situ). Of all B3 subtypes, atypical ductal hyperplasia and flat epithelial atypia were associated with malignancy, whereas only atypical ductal hyperplasia was accompanied by invasive cancer. Of all lesions, flat epithelial atypia was most frequently found in excision specimens (18%). In our study, flat epithelial atypia and atypical ductal hyperplasia are common lesions of the B3 category in needle core biopsies of the breast. Both lesions are associated with malignancy, whereas only atypical ductal hyperplasia was related to invasive cancer. We conclude that an excision biopsy after diagnosis of flat epithelial atypia is recommended depending on clinical and radiologic findings. Copyright 2010 Elsevier Inc.

Women with Low-Risk DCIS Eligible for the LORIS Trial After Complete Surgical Excision: How Low Is Their Risk After Standard Therapy?

Identifying DCIS patients at low risk for disease progression could obviate need for standard therapy. The LORIS (surgery versus active monitoring for low-risk DCIS) trial is studying the safety of monitoring low-risk DCIS, although ipsilateral breast tumor recurrence (IBTR) rates in patients meeting enrollment criteria after complete surgical excision are unknown. Women with pure DCIS treated with breast-conserving surgery (BCS) with/without radiation therapy (RT) from 1/1996-1/2011 were included from a prospectively maintained database. IBTR rates were compared between those who did and did not meet LORIS eligibility criteria (age ≥ 46 years, screen-detected calcifications, nipple discharge absence, minimal family history, non-high-grade DCIS) after complete surgical excision. A total of 2394 women were identified; 401 met LORIS criteria. Median follow-up was 5.9 years; 431 had ≥10 years follow-up. LORIS cohort median age was 61 years (range 46-86 years); 207 (52 %) underwent RT, 79 (20 %) received endocrine therapy. Of 401 patients, 24 experienced an IBTR. Overall 10-year IBTR rates were 10.3 % (LORIS) versus 15.4 % (non-LORIS) (p = 0.08); without RT, 12.1 versus 21.4 %, respectively (p = 0.06). The 10-year invasive-IBTR rates for women meeting LORIS criteria were: 5.3 % BCS overall, 6.0 % without RT. Women meeting LORIS criteria (after complete surgical excision) are at somewhat lower risk for IBTR. Among such women undergoing excision without RT, the 10-year invasive-IBTR rate was 6 %. Given that approximately 20 % of women with core biopsy-proven non-high-grade DCIS have invasive cancer at excision, women managed without excision would be expected to incur higher invasive cancer rates. Additional criteria are needed to identify women not requiring intervention for DCIS.

Historically there has been a high rate of surgical interventions to obtain clear margins for breast cancer patients undergoing breast conserving local therapy. An intraoperative margin assessment tool (MarginProbe) has been approved for use in the US since 2013. This study is the first compilation of data from routine use of the device, to assess the impact of device utilization on re-excision rates. We present a retrospective, observational, review from groups of consecutive patients, before and after the implementation of intraoperative use of the device during lumpectomy procedures. Lesions were localized by standard methods. The intraoperative margin assessment device was used on all circumferential margins of the main specimen, but not on any additional shavings. A positive reading by the device led to an additional shaving of the corresponding cavity location. Specimens were also, when feasible, imaged intra-operatively by X-ray, and additional shavings were taken if needed based on clinical assessment. For each surgeon, historical re-excision rates were established based on a consecutive set of patients from a time period proximal to initiation of use of the device. From March 2013 to April 2014 the device was routinely used by 4 surgeons in 3 centers. In total, 165 cases lumpectomy cases were performed. Positive margins resulted in additional re-excision procedures in 9.7% (16/165) of the cases. The corresponding historical set from 2012 and 2013 consisted of 186 Lumpectomy cases, in which additional re-excision procedures were performed in 25.8% (48/186) of the cases. The reduction in the rate of re-excision procedures was significant 62% (P < 0.0001). Use of an intraoperative margin assessment device contributes to achieving clear margins and reducing re-excision procedures. As in some cases positive margins were found on shavings, future studies of interest may include an analysis of the effect of using the device on the shavings intra-operatively.

Resection of the distal aspect of clavicle has a well-documented treatment modality in case of acromioclavicular joint osteoarthritis resistant to conservative treatment. Limited (mean ∼0.5cm distal end of clavicle resection) distal clavicle excision of A-C joint arthritis in cases resistant to conservative treatment may reduce the pain and improve the shoulder function. In this study, we retrospectively evaluated the results of limited distal clavicle excision of acromioclavicular joint osteoarthritis resistant to conservative treatment. All patients were evaluated by using the Visual Analogue Scale (VAS) and UCLA shoulder rating scale (University of California Los Angeles), either before surgery or final follow-up period for pain and functional results, respectively. A total of 110 patients (48 male, 62 female) with AC joint arthritis, treated between the years of 2008-2012, were retrospectively analyzed. A total of 30 patients (12 male, 18 female) who failed to show improvement with conservative treatment underwent limited surgical open excision of distal clavicle. The mean age of the study population was 52.5±1.2 years. The mean follow-up period was 27±1.3 months. The mean preoperative VAS score was 83.6±5.58 (range, 70-90) while mean VAS was 26.6±9.3 (range, 10-50) at the final follow-up. There was a statistically significant difference between pre- and postoperative VAS scores in patients who had treated by surgical approach (P<0.001). The mean UCLA score of the patients increased postoperatively from 11.5 (range, 9-14) to 29.2 (range, 27-32) at the final follow-up. There was a statistically significant difference between the two time periods with respect to UCLA scores (P<0.001). In patients with AC osteoarthritis resistant to conservative therapy, the hypothesized limited clavicle excision (mean ∼0.5cm distal end of clavicle resection with preserving coracoclavicular ligaments and inferior capsule) reduced the pain and improved the shoulder function. Our midterm follow-up (mean 27 months) results showed that limited distal clavicle excision of patients with AC joint osteoarthritis resistant to conservative treatment (0.5cm distal end of clavicle resection with preserving inferior capsule, and coracoclavicular ligaments) reduced the pain and improved the shoulder function.

2011-11-01

Solitary and multiple cutaneous and mucocutaneous masses were identified in 5 of 24 captive African lions (Panthera leo) over a 6-month-period. All masses were surgically excised, and all were histologically similar to equine and feline sarcoids. DNA was extracted from formalin-fixed, paraffin-embedded tissue. Polymerase chain reaction amplified DNA sequences that had been previously detected in feline sarcoids and clinically normal bovine skin. All lions had been fed a diet that included bovine carcasses that had not been skinned. Since the cessation of feeding bovine carcasses with cutaneous lesions, no additional skin lesions have been observed within any of the lions. Herein is described the clinical, gross, and histopathological findings of sarcoids in 5 captive lions. As the causative papillomavirus most likely has a bovine definitive host, it is hypothesized that the lions were exposed to the virus by feeding on bovine carcasses with skin still attached.

Coal-derived humus: plant growth effects

Freeman, P.G.; Fowkes, W.W.

The growth-promoting properties of coal-derived humus were tested by a variety of bioassay methods. Humate materials used included leonardite, a form of naturally oxidized lignite, and humic acids extracted from leonardite. It was found that the greatest effects were evident when water-soluble humic acid was applied to excised root tips. No significant short-term effect was noted when water-soluble humic acid was applied to stem or coleoptile sections. Root initiation was promoted in bean stems when high concentrations of coal-derived humate were applied. Gross weight of tomato plants was increased by up to 40 percent when coal-derived humates were added inmore » concentrations of 10/sup 1/ to 10/sup 4/ ppM to the nutrient in a hydroponic growth test of 6 weeks' duration. It is concluded that coal-derived humate promotes the uptake of minerals, specifically iron, by serving as a metal chelate.« less

Conservative treatment for breast cancer. Complications requiring reconstructive surgery

Bostwick, J. 3d.; Paletta, C.; Hartrampf, C.R.

Women who select conservative treatment for carcinoma of the breast (tumor excision followed by supervoltage radiation therapy) place a premium on breast preservation and aesthetics. When local control fails and they require a mastectomy, or when the aesthetic appearance is unacceptable, they may request breast reconstruction. The goal of this study is to evaluate a series of 10 patients who required reconstructive breast surgery after complications of conservative treatment. Patient classification: I. Breast or chest wall necrosis (3). II. Breast fibrosis and gross asymmetry (3). III. Local recurrence of breast cancer (5). IV. Positive margins after the initial lumpectomy (1).more » The mean age was 34 years. Radiation dosage average was 5252 rads with two patients receiving iridium-192 implant boosts. The reconstructive management was complex and usually required a major musculocutaneous flap because of the radiation effects.« less

Understanding the needs of families of children and youth with cerebral palsy (CP) is important for family-centred services. The aims of this study were to identify: (1) differences in the number and types of family needs expressed by parents based on the age and gross motor function level of their children with CP; (2) the most frequent family needs; and (3) needs that differ on gross motor function level. A total of 501 parents (77.6% mothers) of children and youth with CP completed a modified version of a Family Needs Survey and a demographic questionnaire. Children's gross motor function level was classified using the Gross Motor Function Classification System. Total number of family needs differed based on gross motor function level (P < 0.001) but not age. Parents of children/youth who use wheeled mobility expressed the highest number of family needs, while parents of children/youth who walk without restrictions expressed the fewest needs. Family needs for Information (P= 0.001), Support (P= 0.001), Community Services (P < 0.001) and Finances (P < 0.001) differed based on children's gross motor function level. Over 50% of parents expressed family needs for information on current and future services, planning for the future, help in locating community activities and more personal time. Parents of children and youth who use wheeled mobility were more likely to express the need for help in paying for home modifications, equipment, services and locating sitters, respite care providers and community activities. The gross motor function of children/youth with CP has implications for collaboration with families to identify needs and co-ordinate services. Health professionals have a role to assist families with information needs and locating community services and leisure activities. Family needs for future planning suggest that health professionals should assist families to prepare for key periods in the lives of their children with CP.

To estimate the prevalence of gross hematuria and urinary retention among men in Sierra Leone and report on barriers to care and associated disability. Gross hematuria and urinary retention are classic urologic complaints that require medical attention for significant underlying pathology, but their burden has not been quantified in a developing country. A cluster randomized, cross-sectional household survey was administered in Sierra Leone using the Surgeons OverSeas Assessment of Surgical need tool as a verbal head-to-toe examination. A total of 2 respondents in each of 25 households in 75 clusters were surveyed to assess surgical needs. Data on questions related to blood from the penis and the inability to urinate for men>12 years were included in the present analysis to determine the period and point prevalence of hematuria and urinary retention. From 3645 total respondents, 1054 (28.9%) were men>12 years included in the analysis. Period and point prevalence of gross hematuria were 21.8 per 1000 (95% confidence interval [CI] 13.0-30.7) and 12.3 per 1000 (95% CI 5.7-19.0), respectively, and for urinary retention, they were 19.9 per 1000 (95% CI 11.5-28.4) and 4.7 per 1000 (95% CI 0.5-8.9), respectively. Lack of financial resources was the major barrier to care. Disability assessment showed 19.1% were not able to work as a result of urinary retention, and 34.8% felt ashamed of their gross hematuria. The results provide a prevalence estimate of gross hematuria and urinary retention for men in Sierra Leone. Accessible medical and surgical care will be critical for early intervention and management. Copyright © 2014 Elsevier Inc. All rights reserved.

The indirect costs of systemic autoimmune diseases, systemic lupus erythematosus, systemic sclerosis and sarcoidosis: a summary of 2012 real-life data from the Social Insurance Institution in Poland.

Kawalec, Paweł P; Malinowski, Krzysztof P

2015-01-01

Systemic lupus erythematosus, systemic sclerosis and sarcoidosis are three different autoimmune systemic diseases that generate a significant burden to society due to treatment costs and also those caused by a work disability or absenteeism among patients. Relevant 2012 data referring to the three components of absenteeism produced by autoimmune systemic diseases, sick leave, short-term and long-term work disability, were obtained from the Social Insurance Institution in Poland (PSII). By applying the Human Capital Approach using gross domestic product per capita, gross value added per worker and gross income per worker in 2012, total indirect costs for the diseases were calculated. All costs were presented in euros and were valid for 2012. The PSII recorded 1600 patients with systemic lupus erythematosus, 500 patients with systemic sclerosis and 2700 patients with sarcoidosis in the 2012 - total indirect costs were as high as 7,260,595, 2,268,571 and 4,027,575 EUR, respectively. Costs were estimated using gross domestic product per capita; 17,485,412, 5,463,312 and 9,699,455 EUR, accordingly, calculated using gross value added per worker and 5,346,933, 1,670,648 and 2,966,034 EUR estimated using gross income per worker, respectively. Considering only data on absenteeism gathered by the PSII we can conclude that the three autoimmune systemic diseases bore great indirect costs. Their social burden for Poland could be even greater when considering presenteeism as well as other components of absenteeism such as loss of unpaid work, a gray economy or loss of leisure time.

2018-01-01

Percutaneous core-needle biopsy (PCNB) is the standard of care to biopsy and diagnose suspicious breast lesions. Dependent on histology, many patients require additional open procedures for definitive diagnosis and excision. This study estimated the payer and patient out-of-pocket (OOP) costs, and complication risk, among those requiring at least 1 open procedure following PCNB. This retrospective study used the Truven Commercial database (2009-2014). Women who underwent PCNB, with continuous insurance, and no history of cancer, chemotherapy, radiation, or breast surgery in the prior year were included. Open procedures were defined as open biopsy or lumpectomy. Study follow-up ended at chemotherapy, radiation, mastectomy, or 90 days-whichever occurred first. In total, 143 771 patients (mean age 48) met selection criteria; 85.1% underwent isolated PCNB, 12.4% one open procedure, and 2.5% re-excision. Incidence of complications was significantly lower among those with PCNB alone (9.2%) vs 1 open procedure (15.6%) or re-excision (25.3%, P  < .001). Mean incremental commercial payments were US $13 190 greater among patients with 1 open procedure vs PCNB alone (US $17 125 vs US $3935, P  < .001), and US $4767 greater with re-excision (US $21 892) relative to 1 procedure. Mean patient OOP cost was US $858 greater for 1 open procedure vs PCNB alone (US $1527 vs US $669), and US $247 greater for re-excision vs 1 procedure. A meaningful proportion of patients underwent open procedure(s) following PCNB which was associated with increased complication risk and costs to both the payer and the patient. These results suggest a need for technologies to reduce the proportion of cases requiring open surgery and, in some cases, re-excision.

To elucidate the proper length and prognostic value of resection margins in rectal cancer patients who received preoperative chemoradiotherapy (CRT) followed by curative total mesorectal excision (TME). A total of 1476 rectal cancer patients staging cT3-4N0-2M0 were analyzed. All patients received radiation dose of 50.4 Gy in 28 fractions with concurrent 5-fluorouracil or capecitabine. Total mesorectal excision was performed 4 to 8 weeks after radiation therapy. The recurrence-free survival (RFS) at 5 years showed a significant difference between 3 groups: patients with circumferential resection margin (CRM) ≤1 mm, CRM 1.1 to 5 mm, and CRM >5 mm (46.2% vs 68.6% vs 77.5%, P<.001). Patients with CRM ≤1 mm showed a significantly higher cumulative incidence of locoregional recurrence (P<.001) and distant metastasis (P<.001) at 5 years compared with the other 2 groups. Patients with CRM 1.1 to 5 mm showed a significantly higher cumulative incidence of distant metastasis (P<.001), but not locoregional recurrence (P=.192), compared with those with CRM >5 mm. Distal resection margin (≤5 vs >5 mm) did not show any significant difference in cumulative incidence of locoregional recurrence (P=.310) and distant metastasis (P=.926). Rectal cancer patients with CRM ≤1 mm are a high-risk group, with the lowest RFS. Patients with CRM 1.1 to 5 mm may be at intermediate risk, with moderately increased distant recurrence. Distal resection margin was not significantly associated with RFS in rectal cancer after neoadjuvant CRT and total mesorectal excision. Copyright © 2017 Elsevier Inc. All rights reserved.

The objective of the present paper is to describe the clinical presentation, diagnostic process, surgical treatment, and outcome of 2 patients with first branchial cleft anomaly. The first case was an 8-year-old girl presented with an elastic lesion located in the left infra-auricular area, in close relation with the lobule, duplicating the external auditory canal. The magnetic resonance imaging revealed a lesion, appearing as a rather well-circumscribed mass within the left parotid gland and duplicating the ear canal. A superficial parotidectomy was subsequently performed, with total excision of the cyst. The second patient was a 15-year-old girl presented with a congenital fistula of the right lateral neck. At superficial parotidectomy, a total excision of the fistula was performed. During the operation the tract was recorded to lay between the branches of the facial nerve, extending with a blind ending canal parallel to the external acoustic meatus. Conclusively, first branchial cleft anomalies are rare malformations with cervical, parotid, or auricular clinical manifestations. Diagnosis of first branchial cleft lesions is achieved mainly through careful physical examination. Complete surgical excision with wide exposure of the lesion is essential in order to achieve permanent cure and avoid recurrence. PMID:23213587

To systematically examine gross motor development in the first 18 months of life of preterm infants. A total of 800 preterm infants (356 boys), ages between 1 and 18 months and corrected for degree of prematurity, were assessed with the use of the Alberta Infant Motor Scale. Comparison of the mean Alberta Infant Motor Scale scores of the preterm infants with the norm-referenced values derived from term infants revealed that as a group, the preterm infants scored significantly lower at all age levels, even with full correction for degree of prematurity. In general, preterm infants exhibit different gross motor developmental trajectories compared with term infants in the first 18 months of life. The gross motor developmental profile of preterm infants may reflect a variant of typical gross motor development, which seems most likely to be specific for this population. As a consequence, adjusted norms should be used for proper evaluation and clinical decision-making in relation to preterm infants.

A 44-year-old man was referred for a right chest nodule of 3 months duration. A 'benign' nodule had been excised from this location 8 years prior. On examination, palpable nodes were noted in the right axilla. Radiographic studies were significant only for right axillary lymphadenopathy. Histologically, a nodular dermal proliferation composed of poorly differentiated epithelioid cells in nests and focally forming ducts with pseudopapillary architecture comprised the primary tumor. Features of a clear cell hidradenoma were noted focally. Immunohistochemical (IHC) analysis revealed reactivity for HMW cytokeratins, CK5 and CK7, p53, p63, CEA (focal), androgen receptor, EGFR, estrogen receptor (ER), MUC5AC, and strong/diffuse membranous staining for Her-2/neu. Negative stains included villin, TTF-1, CDX2, S-100 protein, vimentin, gross cystic disease fluid protein 15 (GCDFP-15), mammoglobulin, and MUC2. A wide local excision and axillary node dissection was performed. Metastatic tumor involved nine of 28 nodes. Interphase fluorescence in situ hybridization (FISH) demonstrated chromosomal amplification of the Her-2/neu locus within the tumor and a nodal metastasis. The patient has completed adjuvant and radiotherapy, including trastuzumab, and is asymptomatic. We believe this to be the first demonstration of Her-2/neu amplification in a malignant skin adnexal tumor. In analogy to breast carcinoma, these findings suggest the applicability of trastuzumab for patients with metastatic adnexal carcinomas demonstrating Her-2/neu amplification.

We describe a novel endoscopic approach and provide a literature review for the "en bloc" dissection of the distal ureter and bladder cuff during laparoscopic radical nephroureterectomy using a transvesical single port approach under pneumovesicum. The procedure was performed in an 80-year old male with a history of gross hematuria due to left renal pelvic TCC and no history of prior bladder TCC. Laparoscopic radical nephroureterectomy was performed and the ureter was dissected down to the bladder and clipped. A single-port device was inserted transvesically and pneumovesicum established. A full thickness incision of the bladder around the ureter was performed with progressive intravesical mobilization of the distal ureter. Subsequently, a water-tight closure of the bladder defect was achieved. The distal ureter, together with the bladder cuff, was then delivered en bloc laparoscopically with the specimen. The operating time (LESS radical nephroureterectomy, RPLND, and bladder cuff excision) was 6hours and 15minutes. The bladder cuff time was 45minutes. There were no intra or postoperative complications and the catheter was removed after 6 days. Histopathological analysis showed kidney-invasive papillary urothelial cancer, pT3 pN0 (0/7) G3. The distal ureter and bladder cuff techniques have not yet been standardized. Management of the bladder cuff with a single port is feasible. Additional studies are needed to identify the best approach for management of the distal ureter at the time of laparoscopic nephroureterectomy. Copyright © 2010 AEU. Published by Elsevier Espana.

Mimosa pudica, commonly known as touch-me-not, is used in folklore medicine in arresting bleeding and in skin diseases. There was no scientific evidence justifying the use of Mimosa pudica, therefore the present study was aimed at evaluation of wound healing activity of the plant. In the present study the roots of Mimosa pudica were studied for wound healing activity by incorporating the methanolic and the total aqueous extract in simple ointment base B.P. in concentration of 0.5% (w/w), 1% (w/w) and 2% (w/w). Wound healing activity was studied in three types of model in rats viz. excision, incision and estimation of biochemical parameter. In case of the excision wound model wound contraction and period of epithelization was studied while in incision wound model was evaluated by determining tensile strength and hydroxyproline content in the scab. Treatment of wound with ointment containing 2% (w/w) the methanolic and 2% (w/w) the total aqueous extract exhibited significant (P<0.001) wound healing activity. The methanolic and total aqueous extracts were analyzed for total phenols content equivalent to Gallic acid. The content of total phenols was 11% (w/w) and 17% (w/w) in methanolic and total aqueous extract respectively. The methanolic extract exhibited good wound healing activity probably due to phenols constituents.

2016-04-01

Although glioblastoma is the most common primary brain tumor, primary intraventricular locations are extremely rare; only 21 cases have been reported to date. A retrospectively acquired database of all intracranial glioblastomas treated in 2 different neurosurgical departments during the last 10 years was queried. Patients with histologically proven intraventricular glioblastomas were included in the study. Eight patients were identified as having a histologically confirmed intraventricular glioblastoma. Patient age at diagnosis ranged from 6 to 74 years (mean 29.6 years) and the male/female ratio was 5:3. Increased intracranial pressure due to hydrocephalus was the main cause of the clinical manifestations. The tumor was located within the lateral ventricle in 6 cases and the anterior third ventricle in 2 others. Gross total tumor excision was achieved in 3 patients, whereas the surgical resection was subtotal in 4 cases and a surgical biopsy was performed in 1 patient. Postoperative adjuvant therapies were administered in 5 patients. Median survival time was 32.1 months, and 3 patients were alive at the end of study. All of them had isocitrate dehydrogenase-mutated tumors. Intraventricular glioblastoma is extremely rare and can affect younger individuals including children. This malignant tumor should be included in the differential diagnosis of intraventricular lesions, especially in the lateral ventricles. Radical surgical resection can be associated with remarkable disease-free survival, especially in isocitrate dehydrogenase-mutated tumors. Because recurrence virtually is unavoidable, long-term follow-up is mandatory. Copyright © 2016 Elsevier Inc. All rights reserved.

Skull base tumors: a comprehensive review of transfacial swing osteotomy approaches.

2005-03-01

Numerous techniques have been proposed for the resection of skull base tumors, each one unique with regard to the region exposed and degree of technical complexity. This study describes the use of transfacial swing osteotomies in accessing lesions located at various levels of the cranial base. Eight patients who underwent transfacial swings for exposure and resection of cranial base lesions between 1996 and 2002 were studied. The mandible was the choice when wide exposure of nasopharyngeal and midline skull base tumors was necessary, especially when they involved the infratemporal fossa. The midfacial swing osteotomy was an option when access to the entire clivus was necessary. An orbital swing approach was used to access large orbital tumors lying inferior to the optic nerve and posterior to the globe, a region that is often difficult to visualize. Gross total tumor excision was possible in all patients. Six patients achieved disease control and two had recurrences. The complications of cerebrospinal fluid leak, infection, hematoma, or cranial nerve damage did not occur. After surgery, some patients experienced temporary symptoms caused by local swelling. The aesthetic result was considered good. Transfacial swing osteotomies provide a wide exposure to tumors that occur in the central skull base area. Excellent knowledge of the detailed anatomy of this region is paramount to the success of this surgery. The team concept is essential; it is built around the craniofacial surgeon and an experienced skull base neurosurgeon.

Speranza, Giovanna; Sultanem, Khalil M.D.; Muanza, Thierry

Purpose: To review and describe our institution's outcomes in patients treated with external beam radiotherapy after keloid excision. Methods and Materials: This was a retrospective study. Patients who received radiotherapy between July 1994 and January 2004 after keloid excision were identified. A questionnaire was mailed regarding sociodemographic factors, early and late radiation toxicities, the need for additional therapy, and satisfaction level. All patients had received a total of 15 Gy in three daily 5-Gy fractions. Treatment started within 24 h after surgery and was delivered on a Siemens orthovoltage machine. The data were analyzed using the STATA statistical package. Results:more » A total of 234 patients were approached. The response rate was 41%, and 75% were female. The mean age was 36.5 years (range, 16-69 years). The patients were mainly of European (53.1%) or African (19.8%) descent. For early toxicity outcomes, 54.2% reported skin redness and 24% reported skin peeling. For late toxicity outcomes, 27% reported telangiectasia and 62% reported permanent skin color changes. No association was found with gender, skin color, or age for the late toxicity outcomes. Of the patients responding, 14.6% required adjuvant treatment. On a visual scale of 1-10 for the satisfaction level, 60% reported a satisfaction level of {>=}8. Telangiectasia was the most significant predictor of a low satisfaction level ({<=}3, p < 0.005). Conclusion: The results of our study have shown that orthovoltage-based radiotherapy after surgical excision for keloids is a good method for the prevention of relapse. It is well tolerated, causes little toxicity, and leads to a high patient satisfaction level.« less

Greece is in an economic crisis compounded by the costs caused by smoking. The present investigation estimates the economic and public health benefits ensuing from the recent cigarette excise tax increase in 2011 and projects the potential benefits from an additional €2.00 per pack cigarette tax increase. The effects of the recent cigarette excise tax increase were calculated on outcome measures: total price per pack, including specific excise, ad valorem tax, and value-added tax consumption; tax revenue; and per capita consumption of cigarettes. Additionally, smoking-attributable mortality, years of potential life lost, and productivity losses were estimated. Projected effects of an additional €2.00 per pack tax increase on consumption and tax revenue were also assessed. The cigarette excise tax increase in 2011 created €558 million in new tax revenue. Cigarette consumption reached a recent low of 24.9 billion sticks sold or 2197 sticks per person in 2011, indicating a 16% decrease in per capita cigarette consumption from the previous year. An additional €2.00 per pack increase in Greek cigarette taxes is projected to result in reduced cigarette sales by an additional 20% and lead to an increase in total cigarette tax revenues by nearly €1.2 billion and the prevention of 192,000 premature deaths. Nations such as Greece, should employ taxation as a crucial measure to promote public health and economic development in such dire times. International economic organisations should aggressively pursue programmes and policies that champion the economic benefits of tobacco taxation. Published by the BMJ Publishing Group Limited.

A simplified gross thrust computing technique for an afterburning turbofan engine

NASA Technical Reports Server (NTRS)

Hamer, M. J.; Kurtenbach, F. J.

1978-01-01

A simplified gross thrust computing technique extended to the F100-PW-100 afterburning turbofan engine is described. The technique uses measured total and static pressures in the engine tailpipe and ambient static pressure to compute gross thrust. Empirically evaluated calibration factors account for three-dimensional effects, the effects of friction and mass transfer, and the effects of simplifying assumptions for solving the equations. Instrumentation requirements and the sensitivity of computed thrust to transducer errors are presented. NASA altitude facility tests on F100 engines (computed thrust versus measured thrust) are presented, and calibration factors obtained on one engine are shown to be applicable to the second engine by comparing the computed gross thrust. It is concluded that this thrust method is potentially suitable for flight test application and engine maintenance on production engines with a minimum amount of instrumentation.

Preservation of anal function after total excision of the anal mucosa for Bowen's disease.

Six women with Bowen's disease of the anogenital area were treated by total excision of the anal mucosa, perianal skin and, in some cases, partial vulvectomy. Two patients had foci of microinvasive squamous carcinoma. Adequate tumor margins were determined by frozen sections. The resulting mucosal and cutaneous defects were grafted with medium split-thickness skin grafts applied to the anal canal and sutured circumferentially to the rectal mucosa. Grafts were held in place by a finger cot inserted in the anal canal and stuffed with cotton balls. Patients were constipated five or six days with codeine. The skin grafts healed per primam. One additional patient was similarly treated for a chronic herpetic ulceration of the anus and healed. Contrary to dire predictions, all patients were able to distinguish between gaseous and solid rectal contents and sphincter function was preserved. In one patient, Bowen's disease has recurred in the grafted perianal skin.

Gamma-ray detector guidance of breast cancer therapy

NASA Astrophysics Data System (ADS)

Ravi, Ananth

2009-12-01

Breast cancer is the most common form of cancer in women. Over 75% of breast cancer patients are eligible for breast conserving therapy. Breast conserving therapy involves a lumpectomy to excise the gross tumour, followed by adjuvant radiation therapy to eradicate residual microscopic disease. Recent advances in the understanding of breast cancer biology and recurrence have presented the opportunity to improve breast conserving therapy techniques. This thesis has explored the potential of gamma-ray detecting technology to improve guidance of both surgical and adjuvant radiation therapy aspects of breast conserving therapy. The task of accurately excising the gross tumour during breast conserving surgery (BCS) is challenging, due to the limited guidance currently available to surgeons. Radioimmuno guided surgery (RIGS) has been investigated to determine its potential to delineate the gross tumour intraoperatively. The effects of varying a set of user controllable parameters on the ability of RIGS to detect and delineate model breast tumours was determined. The parameters studied were: Radioisotope, blood activity concentration, collimator height and energy threshold. The most sensitive combination of parameters was determined to be an 111Indium labelled radiopharmaceutical with a gamma-ray detecting probe collimated to a height of 5 mm and an energy threshold at the Compton backscatter peak. Using these parameters it was found that, for the breast tumour model used, the minimum tumour-to-background ratio required to delineate the tumour edge accurately was 5.2+/-0.4 at a blood activity concentration of 5 kBq/ml. Permanent breast seed implantation (PBSI) is a form of accelerated partial breast irradiation that dramatically reduces the treatment burden of adjuvant radiation therapy on patients. Unfortunately, it is currently difficult to localize the implanted brachytherapy seeds, making it difficult to perform a correction in the event that seeds have been misplaced. One method to provide intraoperative seed localization is through the use of a gamma-camera system. Monte Carlo simulations were conducted of a Cadmium Zinc Telluride (CZT) gamma-camera system and a realistic model of a breast with 3 layers of seeds distributed according to the pre-implant treatment plan of a typical patient. The simulations showed that a gamma-camera was able to localize the seeds with a maximum error of 2.0 mm within 20 seconds. An experimental prototype was designed and constructed to validate these promising Monte Carlo results. Using a 64 pixel linear array CZT detector fitted with a custom built brass collimator, images were acquired of a physical phantom similar to the model used in the Monte Carlo simulations. The experimental prototype was able to reliably detect the seeds within 30 seconds with a median error in localization of 1 mm. The results from this thesis suggest that gamma-ray detecting technology may be able to provide significant improvements in guidance of breast cancer therapies and, thus, potentially improved therapeutic outcomes.

Consensus statement on the multidisciplinary management of patients with recurrent and primary rectal cancer beyond total mesorectal excision planes.

PubMed

2013-07-01

The management of primary rectal cancer beyond total mesorectal excision planes (PRC-bTME) and recurrent rectal cancer (RRC) is challenging. There is global variation in standards and no guidelines exist. To achieve cure most patients require extended, multivisceral, exenterative surgery, beyond conventional total mesorectal excision planes. The aim of the Beyond TME Group was to achieve consensus on the definitions and principles of management, and to identify areas of research priority. Delphi methodology was used to achieve consensus. The Group consisted of invited experts from surgery, radiology, oncology and pathology. The process included two international dedicated discussion conferences, formal feedback, three rounds of editing and two rounds of anonymized web-based voting. Consensus was achieved with more than 80 per cent agreement; less than 80 per cent agreement indicated low consensus. During conferences held in September 2011 and March 2012, open discussion took place on areas in which there is a low level of consensus. The final consensus document included 51 voted statements, making recommendations on ten key areas of PRC-bTME and RRC. Consensus agreement was achieved on the recommendations of 49 statements, with 34 achieving consensus in over 95 per cent. The lowest level of consensus obtained was 76 per cent. There was clear identification of the need for referral to a specialist multidisciplinary team for diagnosis, assessment and further management. The consensus process has provided guidance for the management of patients with PRC-bTME or RRC, taking into account global variations in surgical techniques and technology. It has further identified areas of research priority.

Laparoscopic versus open total mesorectal excision for rectal cancer.

PubMed

Breukink, S; Pierie, J; Wiggers, T

2006-10-18

Because definitive long-term results are not yet available, the oncological safety of laparoscopic surgery for treatment of rectal cancer remains controversial. However, laparoscopic total mesorectal excision (LTME) for rectal cancer has been proposed to have several short-term advantages in comparison with open total mesorectal excision (OTME). To evaluate whether there are any relevant differences in safety and efficacy after elective LTME, for the resection of rectal cancer, compared with OTME. We searched MEDLINE, EMBASE, Cochrane Central register of Controlled Trials (CENTRAL), and Current Contents from 1990 to December 2005. Searches were conducted using MESH terms: "laparoscopy", "minimally invasive","colorectal neoplasms". Furthermore we used the following text words: laparoscopy, surgical procedures, minimally invasive, rectal cancer, rectal carcinoma, rectal adenocarcinoma, rectal neoplasms, anterior resection, abdominoperineal resection, total mesorectal excision. We included randomised controlled trials (RCTs), controlled clinical trials and case series comparing LTME versus OTME. Furthermore case reports which describe LTME were also included. Two reviewers independently assessed study quality. All relevant studies have been categorized according to the evidence they provide according to the guidelines for "Levels of Evidence and Grades of Recommendation" supplied by the "Oxford Centre for Evidence-based Medicine". Disagreements were solved by discussion. 80 studies were identified of which 48 studies, representing 4224 patients, met the inclusion criteria. Methodological quality of most of the included studies was poor; three studies were grade 1b (individual randomised trial), 12 grade 2b (individual cohort study), 5 grade 3b (individual case-control study) and 28 grade 4 (case-series). As only one RCT described primary outcome, 3-year and 5-year disease-free survival rates, no meta-analyses could be performed. No significant differences in terms of disease-free survival rate, local recurrence rate, mortality, morbidity, anastomotic leakage, resection margins, or recovered lymph nodes were found. There is evidence that LTME results in less blood loss, quicker return to normal diet, less pain, less narcotic use and less immune response. It seems likely that LTME is associated with longer operative time and higher costs. No results of quality of life were reported. Based on evidence mainly from non-randomized studies, LTME appears to have clinically measurable short-term advantages in patients with primary resectable rectal cancer. The long-term impact on oncological endpoints awaits the findings from large on-going randomized trials.

Sterba, John A

2006-01-01

The study was designed to examine the effect of adaptive downhill skiing (ADS) on gross motor function in children with spastic cerebral palsy. One girl and four boys participated (mean age = eight years, five months). All were ambulatory. Participants' Gross Motor Function Measure (GMFM) classifications were: Level I (n = 2); Level II (n = 2); Level III (n = 1). ADS was conducted for a 10-week period at one ski resort. Each participant had the same ski instructor. GMFM was obtained every five weeks: beginning five weeks before ADS instruction and continuing to 10 weeks after ADS instruction. After 10 weeks of ADS GMFM-D, and GMFM-Total Score increased 5.4% (p = 0.022) and 3.2% (p = 0.035), respectively, and remained increased 10 weeks after ADS. ADS could be recommended by clinicians as a recreational activity for the gross motor rehabilitation of ambulatory children with spastic cerebral palsy.

To identify the relationship between stimulation at home and motor development among 36 month-old children. The development of gross and fine motor skills of 169 infants (50.9% boys and 49.1% girls) was assessed at the age of 36 months with the Peabody Developmental Motor Scale. The quality of home stimulation was determined during a prior evaluation (at 30 months) by means of the HOME Scale. Total stimulation at home was significantly associated with better performance in the gross and fine motor areas. Particular aspects of this home stimulation were related to better gross and fine motor functions. Static balance and locomotion (gross motor skills) and grasping and visual-motor integration (fine motor skills) are associated with particular aspects of home stimulation, such as parent-child interaction, verbal reinforcement of the child's positive actions and providing the child with clear boundaries.

Objective: To examine the gross pathology and histopathology of ablation zones created from radiofrequency (RF) ablation and to correlate their chronological changes. Methods: A total of 48 in vivo ablation zones (16 rabbit livers) were obtained immediately after and also 30 min, 1 h and 2 h after RF ablation and were subjected to haematoxylin and eosin (H&E) staining, nicotinamide adenine dinucleotide (NADH) diaphorase staining, terminal deoxynucleotidyl transferase dUTP nick end labelling (TUNEL) staining. Chronological changes in gross pathology and histopathology were evaluated and correlated with each other. Results: Peripheral red zones on gross pathology correlated with peripheral zones on H&E staining, lightly stained peripheral zones on NADH staining and peripheral positive zones on TUNEL staining. Central white zones on gross pathology correlated with combined central and border zones on H&E staining, central negative zones on NADH staining and combined central-positive and middle-negative zones on TUNEL staining. Boundary visibility between central white and peripheral red zones on gross pathology was significantly higher at 1 and 2 h than immediately after RF ablation. As time increased after RF ablation, visibility of the border zone on H&E staining and the grade of positively stained hepatocytes in the peripheral zone on TUNEL staining increased. Conclusion: Chronological changes in gross pathology of RF ablation zones correlated well with histopathology. The boundary between the central white and peripheral red zones tended to become clear at 1 h after RF ablation. Advances in knowledge: (1) RF ablation zones show chronological changes on gross pathology and histopathology. (2) Gross pathology and histopathology correlate well with each other. PMID:28139942

1. The potential for the nutritional improvement of pea-based diets by supplementation with a cocktail of exogenous carbohydrases was investigated using growing broiler chicks. 2. Pea meals (grown in the UK) were included in wheat-based diets at 300 g/kg as a partial replacement for an approximately isonitrogenous mixture of wheat and soybean meal. A wheat/soybean meal diet served as a control and each diet was supplemented with a cocktail of alpha-amylase, pectinase and cellulase. The diets were fed to 1-d-old broiler chicks for a period of 21 d. Weight gain and feed conversion were monitored weekly and excreta were collected during the final week in order to determine nutrient digestibility coefficients and metabolisable energy. On d 21, the gastrointestinal (GI) tract was excised and gross morphology measured. 3. Inclusion of pea meal reduced weight gain, feed conversion, nutrient digestibility and also increased the relative sizes of the distal sections of the GI tract. 4. Enzyme addition partially ameliorated the detrimental effects of pea meal inclusion although similar improvements were also noted for birds fed on the control diet. 5. It is concluded that the nutritive value of pea-meal-based diets can be improved by the addition of carbohydrases, and that some pea cultivars show considerable potential as vegetable protein sources for broiler chicks.

To investigate the concurrent validity of AIMS in relation to the gross motor subtest of the Bayley Scale III/GM in preterm infants. A total of 159 gross motor development assessments were performed with the AIMS and Bayley-III/GM. Linear regression was used to assess the correlation between AIMS and Bayley-III/GM scores. The intra-class correlation coefficient (ICC) and the Bland-Altman plot were used to analyze intra- and inter-rater reliability. There was a prevalence of delayed gross motor development of 20.8% according to the Bayley-III/GM, and 11.9% for the 5th percentile and 21.4% for the 10th percentile of AIMS. A good correlation of AIMS with Bayley-III/GM scores and intra- and inter-rater reliability was encountered in this study. AIMS proved very capable of detecting delayed gross motor development in preterm infants when compared with the Bayley-III/GM. The 10th percentile of AIMS provided the best combination of indicators, with greater specificity.

The objective of this study was to investigate the clinical characteristics and surgical modality of plasma cell mastitis (PCM). A total of 93 breasts of 91 female patients with PCM from June 2003 to June 2010 (unilateral in 89 patients and bilateral in two patients) were investigated in this study. All breasts were divided into two groups: the direct excision group (DE group) received focused excision and nipple retraction correction; and the incision drainage group (ID group) received these procedures only in the event of failing at least two incision drainages. Clinical characteristics, extent of excision, and prognosis were compared between two groups. There were 53 breasts in the DE group and 40 breasts in the ID group. No significant differences were noted in the number of retracted nipples and abscesses in the first visit or extent of disease between two groups (P > 0.05). However, during surgery, 3.85 ± 0.97 abscesses per breast were detectable in the ID group, which was significantly higher than 1.21 ± 0.06 abscesses per breast in the DE group. The ID group had significantly higher inflammation and excised extent compared with the DE group (P < 0.05). Hospitalization time was 179.60 ± 14.8 days in the ID group, which was significantly higher than 22.49 ± 1.93 days in the DE group (P < 0.05). Bacterial culture was negative for pus of 39 nonrupturing abscesses. Congenital nipple retraction may be the primary cause of PCM. Early and complete focused excision and nipple retraction correction are effective treatment methods.

Shorea robusta Gaertn.f. (Dipterocarpaceae) resin is used for treating infected wounds and burns by tribals in India. The objective of this study was to investigate wound-healing activity of S. robusta resin extracts and essential oil in rats. Methanol extract (SRME), petroleum ether, benzene insoluble fraction of methanol extract (SRPEBIME), and essential oil (SREO) of S. robusta resin were incorporated in soft yellow paraffin (10% w/w) and applied once daily on incision and excision wounds of Wistar rats. Framycetin ointment (1.0% w/w) was applied to the standard group. Tensile strength (on the 10th day), wound contraction, and scar area (on the 14th day) were recorded. On the 15th day, granulation tissues of excision wounds were analyzed for total protein, hydroxyproline, and hexosamine contents and activities of lipid peroxidation and super oxide dismutase (SOD). Histopathology of the wounds was also studied. SRPEBIME and SREO healed incision and excision wounds faster than plain ointment base and framycetin. Tensile strength of SRPEBIME-treated incision wounds was 53% higher than that of control animals. In excision wounds, wound contraction and scar areas were found to be 99% and 7.7 mm(2) (SRPEBIME) and 71.7% and 21 mm(2) (control). Protein and hydroxyproline contents were higher in SRPEBIME (20.8 and 3.5% w/w) and SREO (17.4 and 2.8% w/w) groups as against 9.95 and 1.48% w/w in control groups. Histopathology revealed complete epithelization and new blood vessel formation in SRPEBIME groups. SRPEBIME and SREO have significant wound-healing activities on incision and excision wounds.

IMPORTANCE Evidence about the efficacy of laparoscopic resection of rectal cancer is incomplete, particularly for patients with more advanced-stage disease. OBJECTIVE To determine whether laparoscopic resection is noninferior to open resection, as determined by gross pathologic and histologic evaluation of the resected proctectomy specimen. DESIGN, SETTING, AND PARTICIPANTS A multicenter, balanced, noninferiority, randomized trial enrolled patients between October 2008 and September 2013. The trial was conducted by credentialed surgeons from 35 institutions in the United States and Canada. A total of 486 patients with clinical stage II or III rectal cancer within 12 cm of the anal verge were randomized after completion of neoadjuvant therapy to laparoscopic or open resection. INTERVENTIONS Standard laparoscopic and open approaches were performed by the credentialed surgeons. MAIN OUTCOMES AND MEASURES The primary outcome assessing efficacy was a composite of circumferential radial margin greater than 1 mm, distal margin without tumor, and completeness of total mesorectal excision. A 6%noninferiority margin was chosen according to clinical relevance estimation. RESULTS Two hundred forty patients with laparoscopic resection and 222 with open resection were evaluable for analysis of the 486 enrolled. Successful resection occurred in 81.7%of laparoscopic resection cases (95%CI, 76.8%–86.6%) and 86.9%of open resection cases (95%CI, 82.5%–91.4%) and did not support noninferiority (difference, −5.3%; 1-sided 95%CI, −10.8%to ∞; P for noninferiority = .41). Patients underwent low anterior resection (76.7%) or abdominoperineal resection (23.3%). Conversion to open resection occurred in 11.3%of patients. Operative time was significantly longer for laparoscopic resection (mean, 266.2 vs 220.6 minutes; mean difference, 45.5 minutes; 95%CI, 27.7–63.4; P < .001). Length of stay (7.3 vs 7.0 days; mean difference, 0.3 days; 95%CI, −0.6 to 1.1), readmission within 30 days (3.3%vs 4.1%; difference, −0.7%; 95%CI, −4.2%to 2.7%), and severe complications (22.5%vs 22.1%; difference, 0.4%; 95%CI, −4.2%to 2.7%) did not differ significantly. Quality of the total mesorectal excision specimen in 462 operated and analyzed surgeries was complete (77%) and nearly complete (16.5%) in 93.5%of the cases. Negative circumferential radial margin was observed in 90% of the overall group (87.9% laparoscopic resection and 92.3%open resection; P = .11). Distal margin result was negative in more than 98%of patients irrespective of type of surgery (P = .91). CONCLUSIONS AND RELEVANCE Among patients with stage II or III rectal cancer, the use of laparoscopic resection compared with open resection failed to meet the criterion for noninferiority for pathologic outcomes. Pending clinical oncologic outcomes, the findings do not support the use of laparoscopic resection in these patients. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00726622 PMID:26441179

An equation for predicting the gross oxygen uptake (gross-VO2) during walking for persons with multiple sclerosis (MS) has been developed. Predictors included walking speed and total score from the 12-Item Multiple Sclerosis Walking Scale (MSWS-12). This study examined the validity of this prediction equation in another sample of persons with MS. Participants were 18 persons with MS with limited mobility problems (42 ± 13 years; 14 women). Participants completed the MSWS-12. Gross-VO2 was measured with open-circuit spirometry during treadmill walking at 2.0, 3.0, and 4.0 mph (0.89, 1.34, and 1.79 m·s(-1)). Absolute percent error was small: 8.3 ± 6.1% , 8.0 ± 5.6% , and 12.2 ± 9.0% at 2.0, 3.0, and 4.0 mph, respectively. Actual gross-VO2 did not differ significantly from predicted gross-VO2 at 2.0 and 3.0 mph, but was significantly higher than predicted gross-VO2 at 4.0 mph (p <  0.001). Bland-Altman plots indicated nearly zero mean difference between actual and predicted gross-VO2 with modest 95% confidence intervals at 2.0 and 3.0 mph, but there was some underestimation at 4.0 mph. Speed and MSWS-12 score provide valid prediction of gross-VO2 during treadmill walking at slow and moderate speeds in ambulatory persons with MS. However, there is a possibility of small underestimation for walking at 4.0 mph.

Size and age of the non structural carbohydrate pool in boreal trees

Autotrophic respiration of trees is supposed to be closely linked to CO2 uptake by photosynthesis on a time scale of days. However, several studies have indicated that roots of boreal trees do not respired carbon (C) with a radiocarbon signature Δ14C similar to that of CO2 in the atmosphere, but C that is 3-4 years old. Also, estimates of gross primary productivity obtained by eddy covariance flux measurements do often not correlate with tree ring width (growth). Both these findings point to the presences of a large non-structural C (NSC) pool within the tree, mainly sugars and starches. The concentration of NSC in tree tissue is considered a measure of C shortage or surplus for growth. Studies indicate that the NSC pool in trees is usually large and relatively constant throughout the year, not affected by e.g. leaf flushing. While estimates of the size of the NSC pool are available for a number of trees from various ecosystems, estimated of its turnover time are lacking. We tested if our finding that boreal trees respire 3-4 year old C is an artifact resulting from the depletion of the NSC pool in excised roots over time. We incubated roots with a diameter of 2-4 mm while they were still attached to the tree, and excised roots after 3 hours, and 1 to 4 days. We sampled CO2 for Δ14C analysis of intact roots, freshly excised roots, and after 1 and 3 days. To obtain an estimate of the NSC pool size and its turnover time in roots of various diameter, we excised and incubated roots of 3 diameters: root hairs with mycorrhizal fungi, 2-4 mm, and 1-2 cm. We followed their respiration over the course of one full day. We will also compare the Δ14C of respired CO2 of freshly root hairs to that of the NSC in the roots. To obtain an estimate of the size and turnover of the whole tree NSC pool, we will measure the Δ14C of NSC in wood. Preliminary results indicate that CO2 fluxes were not correlated to temperature or the initial CO2 concentration in the chamber. While CO2 fluxes of medium and coarse roots remained relatively constant over 4 days, the respiration rates of root hairs declined sharply within the first 24 hours.

Legacy effects of land cover/use on carbon fluxes require considering both present and past land cover/use change dynamics. To assess past land use dynamics, model-based reconstructions of historic land cover/use are needed. Most historic reconstructions consider only the net area difference between two time steps (net changes) instead of accounting for all area gains and losses (gross changes). Studies about the impact of gross and net land change accounting methods on the carbon balance are still lacking. In this study, we assessed historic changes in carbon in soils for five land cover/use types and of carbon in above-ground biomass of forests. The assessment focused on Europe for the period 1950 to 2010 with decadal time steps at 1-km spatial resolution using a bookkeeping approach. To assess the implications of gross land change data, we also used net land changes for comparison. Main contributors to carbon sequestration between 1950 and 2010 were afforestation and cropland abandonment leading to 14.6 PgC sequestered carbon (of which 7.6 PgC was in forest biomass). Sequestration was highest for old-growth forest areas. A sequestration dip was reached during the 1970s due to changes in forest management practices. Main contributors to carbon emissions were deforestation (1.7 PgC) and stable cropland areas on peaty soils (0.8 PgC). In total, net fluxes summed up to 203 TgC yr(-1) (98 TgC yr(-1) in forest biomass and 105 TgC yr(-1) in soils). For areas that were subject to land changes in both reconstructions (35% of total area), the differences in carbon fluxes were about 68%. Overall for Europe the difference between accounting for either gross or net land changes led to 7% difference (up to 11% per decade) in carbon fluxes with systematically higher fluxes for gross land change data. © 2015 John Wiley & Sons Ltd.

Early and Long-Term Outcomes of Patients Undergoing Liver Resection and Diaphragm Excision for Advanced Colorectal Liver Metastases

INTRODUCTION At present, liver resection offers the best long-term outcome and only chance for cure in patients with colorectal liver metastases. However, there are no large series that report the early and long-term outcomes of patients who require simultaneous diaphragm excision. This study was designed to investigate these patients. PATIENTS AND METHODS A total of 285 consecutive liver resections were performed over a 10-year period. Of these, 258 had liver resections alone and 27 underwent liver resection and simultaneous diaphragm excision. Data were collected prospectively and analysed retrospectively. Pre-operative assessment was standardised. The outcomes between the two groups were compared. RESULT There was no difference in age, hospital stay or intra-operative blood loss. The diaphragm was histologically involved in four out of 27 resections. As a result, the cancer involved resection margin incidence was greater in the liver resection and diaphragm excision group (14.8% versus 3.9%; P = 0.12). The median tumour size was also different between the two groups (60 mm versus 30 mm; P = 0.001). The liver and diaphragm resection group had a greater peri-operative complication rate (44.4% versus 21.3%; P = 0.02) and mortality (7.4% versus 1.6%; P = 0.25). Overall and disease-free survival was significantly worse in the group who underwent simultaneous diaphragm excision and liver resection (P = 0.04 and P = 0.005, respectively). Diaphragm invasion was found to be an independent predictor of poor overall outcome (P = 0.02). CONCLUSION Liver resection and simultaneous diaphragm excision have a greater incidence of peri-operative morbidity and mortality and a significantly worse long-term outcome compared with liver resection alone. However, these data suggest that liver resection in the presence of diaphragm invasion may still offer a favourable outcome compared with chemotherapy treatment alone. Therefore, we believe that diaphragm involvement by tumour should not be a contra-indication to hepatectomy. PMID:19558763

The impact of surgery on survival of patients with cutaneous melanoma: revisiting the role of primary tumor excision margins.

2011-02-01

To quantify the impact of excision margins on disease-specific survival of patients with primary cutaneous melanoma. Current guidelines recommend narrow margins for the treatment of primary melanoma, although available evidence on this subject is not unequivocal and not always appropriately analyzed. A systematic review of randomized controlled trials (RCT) addressing the issue of wide versus narrow excision margins was performed. Meta-analysis methods for time-to-event data were used to extract hazard ratios(HR) and their 95% confidence intervals (CI) from eligible studies, and ultimately to estimate the summary effect of excision margins on patients' survival. The 5 eligible RCT enrolled a total of 3295 patients who were allocated to wide (3-5 cm) or narrow (1-2 cm) excision of their primary tumor. The data of locoregional disease-free (LDFS), disease-free (DFS),disease-specific (DSS), and overall (OS) survival were available for 3, 5, 3, and 5 RCT, respectively. The meta-analysis suggested that narrow margins might be associated with an increased risk of both locoregional disease recurrence (HR: 1.30, CI: 1.07-1.57; P = 0.01) and death by disease (HR: 1.28, CI:1.07-1.53, P = 0.01). As regards DFS, the borderline disadvantage (HR:1.13, CI: 0.995-1.28; P = 0.06) becomes significant when considering RCT that enrolled patients with thicker melanoma (HR: 1.19, CI: 1.02-1.39, P =0.03). When death by any cause (OS) was analyzed, no risk difference was found. The lack of DSS data from all the available RCT does not allow to draw definitive conclusions. However, current evidence appears sufficient to question the common belief that narrow excision margins are as safe as wide margins in the management of primary melanoma, that calls for further investigation in this field.

Amino acid and N mineralization dynamics in heathland soil after long-term warming and repetitive drought

NASA Astrophysics Data System (ADS)

Andresen, L. C.; Bode, S.; Tietema, A.; Boeckx, P.; Rütting, T.

2015-04-01

Monomeric organic nitrogen (N) compounds such as free amino acids (FAAs) are an important resource for both plants and soil microorganisms and a source of ammonium (NH4+) via microbial FAA mineralization. We compared gross FAA dynamics with gross N mineralization in a Dutch heathland soil using a 15N tracing technique. A special focus was made on the effects of climate change factors warming and drought, followed by rewetting. Our aims were to (1) compare FAA mineralization (NH4+ production from FAAs) with gross N mineralization, (2) assess gross FAA production rate (depolymerization) and turnover time relative to gross N mineralization rate, and (3) assess the effects of a 14 years of warming and drought treatment on these rates. The turnover of FAA in the soil was ca. 3 h, which is almost 2 orders of magnitude faster than that of NH4+ (i.e. ca. 4 days). This suggests that FAA is an extensively used resource by soil microorganisms. In control soil (i.e. no climatic treatment), the gross N mineralization rate (10 ± 2.9 μg N g-1 day-1) was 8 times smaller than the total gross FAA production rate of five AAs (alanine, valine, leucine, isoleucine, proline: 127.4 to 25.0 μg N g-1 day-1). Gross FAA mineralization (3.4 ± 0.2 μg N g-1 day-1) contributed 34% to the gross N mineralization rate and is therefore an important component of N mineralization. In the drought treatment, a 6-29% reduction in annual precipitation caused a decrease of gross FAA production by 65% and of gross FAA mineralization by 41% compared to control. On the other hand, gross N mineralization was unaffected by drought, indicating an increased mineralization of other soil organic nitrogen (SON) components. A 0.5-1.5 °C warming did not significantly affect N transformations, even though gross FAA production declined. Overall our results suggest that in heathland soil exposed to droughts a different type of SON pool is mineralized. Furthermore, compared to agricultural soils, FAA mineralization was relatively less important in the investigated heathland. This indicates more complex mineralization dynamics in semi-natural ecosystems.

Background Poor motor skills have been consistently linked with a higher body weight in childhood, but the causal direction of this association is not fully understood. This study investigated the temporal ordering between children’s motor skills and weight status at 5 and 10 years. Methods Participants were 668 children (54% male) who were studied from infancy as part of an iron-deficiency anemia preventive trial and follow-up study in Santiago, Chile. All were healthy, full term, and weighing 3 kg or more at birth. Cross-lagged panel modeling was conducted to understand the temporal precedence between children’s weight status and motor proficiency. Analyses also examined differences in gross and fine motor skills among healthy weight, overweight, and obese children. Results A higher BMI at 5 years contributed to declines in motor proficiency from 5 to 10 years. There was no support for the reverse; that is, poor motor skills at 5 years did not predict increases in relative weight from 5 to 10 years. Obesity at 5 years also predicted declines in motor proficiency. When compared to normal weight children, obese children had significantly poorer total and gross motor skills at both 5 and 10 years. Overweight children had poorer total and gross motor skills at 10 years only. The differences in total and gross motor skills among normal-weight, overweight, and obese children appear to increase with age. There were small differences in fine motor skill between obese and non-obese children at 5 years only. Conclusions Obesity preceded declines in motor skills and not the reverse. Study findings suggest that early childhood obesity intervention efforts might help prevent declines in motor proficiency which, in turn, may positively impact children’s physical activity and overall fitness levels.

Participants were 668 children (54% male) who were studied from infancy as part of an iron deficiency anaemia preventive trial and follow-up study in Santiago, Chile. All were healthy, full-term and weighing 3 kg or more at birth. Cross-lagged panel modelling was conducted to understand the temporal precedence between children's weight status and motor proficiency. Analyses also examined differences in gross and fine motor skills among healthy weight, overweight, and obese children. A higher BMI at 5 years contributed to declines in motor proficiency from 5 to 10 years. There was no support for the reverse, that is, poor motor skills at 5 years did not predict increases in relative weight from 5 to 10 years. Obesity at 5 years also predicted declines in motor proficiency. When compared with normal weight children, obese children had significantly poorer total and gross motor skills at both 5 and 10 years. Overweight children had poorer total and gross motor skills at 10 years only. The differences in total and gross motor skills among normal weight, overweight and obese children appear to increase with age. There were small differences in fine motor skill between obese and non-obese children at 5 years only. Obesity preceded declines in motor skills and not the reverse. Study findings suggest that early childhood obesity intervention efforts might help prevent declines in motor proficiency that, in turn, may positively impact children's physical activity and overall fitness levels. © 2016 John Wiley & Sons Ltd.

A plan was developed during 1971 to determine gross tectonic plate motions along the San Andreas Fault System in California. Knowledge of the gross motion along the total fault system is an essential component in the construction of realistic deformation models of fault regions. Such mathematical models will be used in the future for studies which will eventually lead to prediction of major earthquakes. The main purpose of the experiment described is the determination of the relative velocity of the North American and the Pacific Plates. This motion being so extremely small, cannot be measured directly but can be deduced from distance measurements between points on opposite sites of the plate boundary taken over a number of years.

2018-03-01

In this paper, an application of Robust Optimization in agricultural water resource management problem under gross margin and water demand uncertainty is presented. Water resource management is a series of activities that includes planning, developing, distributing and managing the use of water resource optimally. Water resource management for agriculture can be one of the efforts to optimize the benefits of agricultural output. The objective function of agricultural water resource management problem is to maximizing total benefits by water allocation to agricultural areas covered by the irrigation network in planning horizon. Due to gross margin and water demand uncertainty, we assume that the uncertain data lies within ellipsoidal uncertainty set. We employ robust counterpart methodology to get the robust optimal solution.

Six women with Bowen's disease of the anogenital area were treated by total excision of the anal mucosa, perianal skin and, in some cases, partial vulvectomy. Two patients had foci of microinvasive squamous carcinoma. Adequate tumor margins were determined by frozen sections. The resulting mucosal and cutaneous defects were grafted with medium split-thickness skin grafts applied to the anal canal and sutured circumferentially to the rectal mucosa. Grafts were held in place by a finger cot inserted in the anal canal and stuffed with cotton balls. Patients were constipated five or six days with codeine. The skin grafts healed per primam. One additional patient was similarly treated for a chronic herpetic ulceration of the anus and healed. Contrary to dire predictions, all patients were able to distinguish between gaseous and solid rectal contents and sphincter function was preserved. In one patient, Bowen's disease has recurred in the grafted perianal skin. Images Fig. 1. Fig. 2. Fig. 3. Fig. 4. Fig. 5. Fig. 6. PMID:6372711

Laparoscopic and Robotic Total Mesorectal Excision in the Treatment of Rectal Cancer. Brief Review and Personal Remarks

The current standard treatment for rectal cancer is based on a multimodality approach with preoperative radiochemotherapy in advanced cases and complete surgical removal through total mesorectal excision (TME). The most frequent surgical approach is traditional open surgery, as laparoscopic TME requires high technical skill, a long learning curve, and is not widespread, still being confined to centers with great experience in minimally invasive techniques. Nevertheless, in several studies, the laparoscopic approach, when compared to open surgery, has shown some better short-term clinical outcomes and at least comparable oncologic results. Robotic surgery for the treatment of rectal cancer is an emerging technique, which could overcome some of the technical difficulties posed by standard laparoscopy, but evidence from the literature regarding its oncologic safety and clinical outcomes is still lacking. This brief review analyses the current status of minimally invasive surgery for rectal cancer therapy, focusing on oncologic safety and the new robotic approach. PMID:24834429

For rapid, intra-operative pathological margin assessment to guide staged cancer excisions, multimodal confocal mosaic scan image wide surgical margins (approximately 1 cm) with sub-cellular resolution and mimic the appearance of conventional hematoxylin and eosin histopathology (H&E). The goal of this work is to combine three confocal imaging modes: acridine orange fluorescence (AO) for labeling nuclei, eosin fluorescence (Eo) for labeling cytoplasm, and endogenous reflectance (R) for marking collagen and keratin. Absorption contrast is achieved by alternating the excitation wavelength: 488 nm (AO fluorescence) and 532 nm (Eo fluorescence). Superposition and false-coloring of these modes mimics H&E, enabling detection of cutaneous squamous cell carcinomas (SCC). The sum of mosaic Eo+R is false-colored pink to mimic the appearance of eosin, while the AO mosaic is false-colored purple to mimic the appearance of hematoxylin in H&E. In this study, mosaics of 10 Mohs surgical excisions containing invasive SCC, and five containing only normal tissue were subdivided for digital presentation equivalent to 4× histology. Of the total 50 SCC and 25 normal sub-mosaics presented, two reviewers made two and three type-2 errors (false positives), respectively. Limitations to precisely mimic H&E included occasional elastin staining by AO. These results suggest that confocal mosaics may effectively guide staged SCC excisions in skin and other tissues.

Spinal arachnoid cysts (SACs) are filled with cerebrospinal fluid, and they include the arachnoid membrane, making it difficult to distinguish the walls of the cyst from the arachnoid membrane and excise the cyst as a lump. Here we report a technique for the intraoperative visualization of SACs, involving the use of pyoktanin blue. Four patients with spinal intradural arachnoid cysts underwent total excision of the cysts between October 2016 and April 2017. In 1 case, magnetic resonance imaging revealed the cyst clearly, but in the other cases, the cysts were unclear. All cysts were injected with 1% pyoktanin blue (Wako Pure Chemical Industries, Osaka, Japan) diluted 500 times with physiological saline before excision. When it was difficult to distinguish the cyst from the normal arachnoid membrane, 1% pyoktanin blue diluted 1000 times with physiological saline was injected into both the cyst and the subarachnoid space, and the spread of the stain was observed. The cysts were better visualized after pyoktanin blue injection than before injection. When it was difficult to distinguish the cyst from the normal arachnoid space, pyoktanin blue injection was useful for judging the cyst space. There were no perioperative complications, and the patients' symptoms improved partially or completely after treatment. Our technique of pyoktanin blue injection into SACs could make their excision easy and safe. Copyright © 2017 Elsevier Inc. All rights reserved.

Although red laser lights lie in the region of non-ionizing radiations in the electromagnetic spectrum, there are doubts whether absorption of these radiations causes lesions in the DNA molecule. Our aim was to investigate the expression of the genes involved with base excision and nucleotide excision repair pathways in skin tissue submitted to burn injury and exposed to low-level red laser. Wistar rats were divided as follows: control group-rats burned and not irradiated, laser group-rats burned and irradiated 1 day after injury for five consecutive days, and later laser group-rats injured and treated 4 days after injury for five consecutive days. Irradiation was performed according to a clinical protocol (20 J/cm(2), 100 mW, continuous wave emission mode). The animals were sacrificed on day 10, and scarred tissue samples were withdrawn for total RNA extraction, complementary DNA (cDNA) synthesis, and evaluation of gene expression by quantitative polymerase chain reaction. Low-level red laser exposure (1) reduces the expression of APE1 messenger (mRNA), (2) increases the expression of OGG1 mRNA, (3) reduces the expression of XPC mRNA, and (4) increases the expression of XPA mRNA both in laser and later laser groups. Red laser exposure at therapeutic fluences alters the expression of genes related to base excision and nucleotide excision pathways of DNA repair during wound healing of burned skin.

Abstract. For rapid, intra-operative pathological margin assessment to guide staged cancer excisions, multimodal confocal mosaic scan image wide surgical margins (approximately 1 cm) with sub-cellular resolution and mimic the appearance of conventional hematoxylin and eosin histopathology (H&E). The goal of this work is to combine three confocal imaging modes: acridine orange fluorescence (AO) for labeling nuclei, eosin fluorescence (Eo) for labeling cytoplasm, and endogenous reflectance (R) for marking collagen and keratin. Absorption contrast is achieved by alternating the excitation wavelength: 488 nm (AO fluorescence) and 532 nm (Eo fluorescence). Superposition and false-coloring of these modes mimics H&E, enabling detection of cutaneous squamous cell carcinomas (SCC). The sum of mosaic Eo+R is false-colored pink to mimic the appearance of eosin, while the AO mosaic is false-colored purple to mimic the appearance of hematoxylin in H&E.

Recently, the Long Term Storage Facility (LTSF) in Bukit Kledang, Perak, Malaysia, has been upgraded to repository facility upon the completion of decontamination and decommissioning (D&D) process. Thorium waste and contaminated material that may contain some minor amounts of thorium hydroxide were disposed in this facility. This study is conducted to determine the concentrations of gross alpha and gross beta radioactivities in soil samples collected around the repository facility. A total of 12 soil samples were collected consisting 10 samples from around the facility and 2 samples from selected residential area near the facility. In addition, the respective dose rates were measured 5 cm and 1 m above the ground by using survey meter with Geiger Muller (GM) detector and Sodium Iodide (NaI) detector. Soil samples were collected using hand auger and then were taken back to the laboratory for further analysis. Samples were cleaned, dried, pulverized and sieved prior to analysis. Gross alpha and gross beta activity measurements were carried out using gas flow proportional counter, Canberra Series 5 XLB - Automatic Low Background Alpha and Beta Counting System. The obtained results show that, the gross alpha and gross beta activity concentration ranged from 1.55 to 5.34 Bq/g with a mean value of 3.47 ± 0.09 Bq/g and 1.64 to 5.78 Bq/g with a mean value of 3.49 ± 0.09 Bq/g, respectively. These results can be used as an additional data to represent terrestrial radioactivity baseline data for Malaysia environment. This estimation will also serve as baseline for detection of any future related activities of contamination especially around the repository facility area.

Spinal osteoid osteomas are benign primary tumors arising predominantly from the posterior column of the spine. These "osteoblastic" lesions have traditionally been treated with intralesional excision. The purpose of the present study was to review the treatment and local recurrence rates for symptomatic spinal osteoid osteomas. Multicenter ambispective cross-sectional observational cohort study. During the study period, a total of 84 patients (65 males, 19 females) were diagnosed with a spinal osteoid osteoma and received surgical treatment. The mean age at surgery was 21.8 ± 9.0 years (range: 6.7-52.4 years) and the mean follow-up was 2.7 years (13 days-14.5 years). Local recurrence, perioperative morbidity, and cross-sectional survival. Using the AOSpine Knowledge Forum Tumor multicenter ambispective database, surgically treated osteoid osteoma cases were identified. Patient demographic, clinical and diagnostic, treatment, local recurrence, perioperative morbidity, and cross-sectional survival data were collected and retrieved. Descriptive statistics were summarized using mean/standard deviation or frequency/percentage. In our study, most of the tumors were localized in the mobile spine (81 of 84 [96%]); all patients reported pain as a symptom. According to the postoperative assessment, 10 (12%) patients received an en bloc resection with marginal or wide margins, whereas two (2%) patients received en bloc resections with intralesional margins, 69 (82%) patients were treated by piecemeal "intralesional" resection, and three (4%) patients were not assessed. A total of six patients (7%) experienced a local recurrence, all of which occurred in patients who had received an intralesional resection. Benign bone-forming tumors of the spine are uncommon. Most patients in our series underwent a piecemeal resection with intralesional margins. This remains safe with a low local recurrence rate. En bloc excision may provide more chance of complete excision of the nidus but is not mandatory. The importance of complete excision of the nidus cannot be overemphasized.

Good oncologic outcomes, demonstrated by a complete pathologic response after preoperative chemoradiotherapy (PCRT), have led to local excision (LE) in selected patients with rectal cancer. We evaluated the oncologic safety of LE compared with total mesorectal excision (TME) in patients with ypT0-T1 rectal cancer.A retrospective review of 304 patients who underwent PCRT, followed by LE or TME, for ypT0-T1 rectal cancer was performed. Propensity scores were computed and used to match groups (LE:TME = 1:1), and analysis of disease-free survival (DFS) and overall survival (OS) was made by comparing patients who underwent LE or TME. Prognostic factors of relapse were analyzed for all patients.Tumor categories were ypT0 in 25 (61.9%) cases, ypTis in 6 (14.3%) cases, and ypT1 in 11 (26.2%) cases for the LE group, and ypT0 in 28 (66.7%) cases, ypTis in 4 (9.5%) cases, and ypT1 in 10 (23.8%) cases for the matched TME patients. There was no significant difference between the matched LE and TME groups in relapse (4.8% and 7.14%, respectively; P = 0.646), 5-year DFS (95.2% vs 91.6%; P = 0.33) and 5-year OS (96.6% vs 88.0%; P = 0.238). In the multivariate Cox regression analysis, tumor distance from the anal verge (hazard ratio [HR] = 0.78; 95% confidence interval (CI) = 0.616-0.992) and the tumor grade (HR = 4.29; 95% CI = 1.430-12.886) were significantly associated with the recurrence risk.LE results in oncologic outcomes that are comparable to those achieved by TME in selected patients with ypT0-T1 rectal cancer after PCRT.

Bilateral axillary hidradenitis is a chronic, suppurative, and scarring disease that is most effectively treated by complete excision of all hair-bearing tissues. We assessed our staged procedure for excision and placement of a split-thickness skin graft for bilateral axillary hidradenitis in terms of costs, outcomes, and timing of excision. An IRB approved retrospective case analysis was performed on patients that underwent bilateral axillary hidradenitis skin excision with eventual placement of split-thickness skin grafting using the current LSUHSC/University Health hidradenitis surgical treatment protocol. Using ICD-9 codes (705.83) and CPT codes (11041, 11042, 11451, 11600, 11601, 11602, 11603, 11604) we reviewed cases performed at our institution from 1 January 2008 to 24 Febuary 2014 and we selected patients based on bilateral axillary involvement (alone) and >1 year history of active disease. Patients were excluded if resection of tissue encompassed regions outside of the immediately adjacent axillary. A total of seven patients matching criteria for bilateral axillary hidradenitis were selected for analysis. Clinical course, cost and surgical techniques were assessed. Of the seven patients, six required admission throughout their treatment due to lack of funding making use of negative pressure wound therapy at home not possible. These patients stayed an average of 10 days with a mean hospital charge of $35,178 and a mean hospital provider charge of $10,019. No recurrence was demonstrated. All patients attained full range of motion, post grafting. No patient required a further operation due to graft failure. Split-thickness skin grafting without use of bilayer dermal regenerative templates yielded definitive results with acceptable cosmesis and functionality, without the added cost of treatments such as a bilayer dermal regenerative template.

(i) To report the successful treatment of 10 cases of equine periocular squamous cell carcinoma (PSCC) with surgical excision and photodynamic therapy (PDT) using verteporfin. (ii) To evaluate time to first tumor recurrence between PDT-treated horses and horses treated with surgical excision and cryotherapy. A total of 24 equine PSCC cases were included: group 1 (n = 14) had excision and cryotherapy (1993–2003), group 2 (n = 10), excision and local PDT (2006–2010). Evaluated data: signalment, treatment method, tumor location, size, and time to first recurrence. Groups were compared via chi-square test for categorical variables and Wilcoxon rank-sum test for numeric variables. Time to tumor recurrence was examined using Kaplan–Meier product-limit survival analysis. Of 24 cases, nine breeds were affected. Mean age at treatment in years: 14 (range 5–24) in group 1; 11 (range 8–18) in group 2. Median tumor size: 163 mm2 (range 20–625 mm2) in group 1; 195 mm2 (range 45–775 mm2) in group 2. Signalment, tumor laterality, and size were not significantly different between groups. Time to recurrence was significantly different between groups (Logrank test, P = 0.0006). In group 1, 11/14 horses had tumor regrowth with median time to recurrence in months: 10 (range 1–44). In group 2 (minimum follow-up of 25 months; range 25–50), no horse demonstrated tumor recurrence after one treatment with excision and PDT. This represents the first report of local PDT using verteporfin for treatment of equine PSCC. Following surgery, the likelihood of tumor recurrence was significantly reduced with local PDT compared with cryotherapy. © 2013 American College of Veterinary Ophthalmologists.

Aim of the study was the evaluation of the role of adjuvant radiation therapy in the prevention of recurrence after excision. Between July 1, 1985 and April 1, 1993, 64 patients (43 male, 21 female) were referred to radiation therapy after excision of a nasal pterygium. Radiation therapy was done with a strontium-90 eye applicator and a total dose of 30 Gy, fractionated in 6 fractions of 5 Gy each, 3 times a week. Forty-nine patients were treated primarily, 15 patients underwent radiation therapy for the first time in case of recurrent pterygium after multiple re-excisions. All patients had a following of 1 to 9 years with a median of 5.5 years. In 8 of 64 irradiated patients recurrent pterygium was detected (12.5%). Differentiated into the 2 groups 4 of the primarily treated patients had recurrent pterygium (8.16%), the other 4 were in the group with multiple former re-excisions (26.7%). With regard to the initiation of the irradiation after surgery pterygium did not recur in any of the primarily treated patients who were irradiated in between 3 days after surgery. In contrary 3 of 7 primarily treated patients (42.9%) who started radiation therapy between 7 and 10 days after surgery had recurrent pterygium. For the patients with primarily recurrent pterygium no dependence of the initiation of radiation therapy after surgery could be detected. Adjuvant radiation therapy after excision of pterygium lowers the rate of recurrence from about 40% to 12.5%, in a primarily adjuvant situation to 8.16%. In these patients radiation therapy should be initiated within 3 days after surgery. Patients with primarily recurrent pterygium have an elevated risk of recurrence independently of the initiation of radiation therapy.

This study examined the gross grasp strength and fine motor dexterity of adolescents, who are diagnosed with multiple sclerosis (MS). A total sample size of 72 participants between the ages of 13 to 17 was studied. Thirty six with a diagnosis of pediatric relapse remitting MS and 36 matched control participants were selected from various local youth groups. Data on hand strength and dexterity was collected using a dynamometer, nine hole peg board and Purdue pegboard on both groups. Utilizing ANCOVA to describe the differences across the two groups by diagnosis, controlling for age and gender, it was found that the MS group demonstrated significantly decreased dexterity when compared to age and gender matched controls. There was no significant difference in gross grasp strength by diagnostic group. This preliminary study showed that children with a diagnosis of pediatric MS may have differences in fine motor dexterity, but not gross grasp strength from their peers who do not have the diagnosis. Further study is indicated to examine this phenomenon.

The social costs of alcohol misuse in Estonia.

2009-01-01

The aim of this study was to estimate the social costs of alcohol misuse in Estonia in 2006. Using a prevalence-based cost-of-illness approach, both direct and indirect costs were considered, including tangible costs associated with health care, criminal justice, rescue services, damage to property, premature mortality, incarceration, incapability of working due to illnesses, and lower labor productivity. The results show that alcohol misuse cost Estonia more than EUR 200 million in 2006. The costs involved are estimated to represent 1.6% of the gross domestic product (GDP), which is relatively high in comparison with many other countries. In addition, the state receives less receipts from the alcohol excise tax than the costs that it incurs as a consequence of alcohol misuse, which points to the existence of economic inefficiency with respect to the alcohol market. The results of this study suggest that there is definitely a need for further cost-benefit analysis to reach a conclusion regarding the possible utility of government intervention. Copyright 2008 S.

The level of natural radioactivity for Bolu province of north-western Turkey was assessed in this study. There is no information about radioactivity measurement reported in water samples in the Bolu province so far. For this reason, gross α and β activities of 55 different water samples collected from tap, spring, mineral, river and lake waters in Bolu were determined. The mean activity concentrations were 68.11 mBq L(-1), 169.44 mBq L(-1) for gross α and β in tap water. For all samples the gross β activity is always higher than the gross α activity. All value of the gross α were lower than the limit value of 500 mBq L(-1) while two spring and one mineral water samples were found to have gross β activity concentrations of greater than 1000 mBq L(-1). The associated age-dependent dose from all water ingestion in Bolu was estimated. The total dose for adults had an average value exceeds the WHO recommended limit value. The risk levels from the direct ingestion of the natural radionuclides in tap and mineral water in Bolu were determinated. The mean (210)Po and (228)Ra risk the value of tap and mineral waters slightly exceeds what some consider on acceptable risk of 10(-4) or less. Copyright © 2014 Elsevier Ltd. All rights reserved.

Effect of mitomycin C on keloid fibroblasts: an in vitro study.

2003-01-01

Keloids are the result of aberrant wound healing of human skin after dermal injury. Therapeutic options include excision followed by radiation therapy, steroid injection, and compression with silicone sheets among others. Local invasion and recurrence after excision has provoked interest in treating keloids as neoplasms. The purpose of this study was to determine the effect of mitomycin C (MMC) on keloid fibroblasts. Keloid fibroblasts obtained from five different patients were exposed to MMC. A control group of normal and keloid cells was treated with phosphate buffered saline only. Contrast microscopy showed a decrease of fibroblast density during the 3 weeks after exposure for normal and keloid fibroblasts relative to untreated fibroblasts. This was confirmed by total cell counts ( = 0.1) and measurement of DNA synthesis. By the third week, there was a recovery in DNA synthesis and increased cell count for some of the treated fibroblasts. We concluded that at an appropriate concentration, MMC shows proliferation of keloid fibroblasts in vitro for a period of 3 weeks. This agent may be considered in clinical trials after surgical excision of keloids.

FEA lesions group two histological types: columnar cell hyperplasia with atypia (CCHA) and columnar cell change with atypia (CCA). The increasing use of VAB has resulted in increased detection of isolated FEA lesions. The aim of this study was to define the best management possible for these patients: which cases may not need excision? From our database of 780 VABs carried out from 2000 to 2004, 59 patients with FEA were diagnosed. Cases in which no surgery was performed or all features were not available were excluded, thus excluding 19 cases. Forty patients with FEA were included. We reviewed clinical and mammographic characteristics, histological biopsy, and the corresponding surgically excised tissue features. VAB yielded 25 cases of CCHA and 15 cases of CCA. Surgery revealed seven ductal carcinoma cases (four invasive, three in situ); nine benign lesions, and 24 with atypia (19 FEA and six atypical ductal hyperplasia). We found two features related to the risk of cancer: the presence and the size of hyperplasia. All carcinomas were found within the CCHA lesions. No cancer was yielded when size was less than 10 mm within CCA lesions and lesions that were totally removed. We recommend surgical excision when CCHA greater than 10 mm is found on the VAB or it is incompletely removed. CCA lesions or CCHA less than 10 mm or totally removed may obviate systematic surgery.

Craniopharyngiomas are dysontogenic tumors with benign histology but aggressive behavior. The surgical challenges posed by the tumor are well recognized. Neuroendoscopy has recently contributed to its surgical management. This study focuses on our experience in managing craniopharyngiomas in recent years, highlighting the role of combined endoscopic trans-ventricular and endonasal approach. Ninety-two patients have been treated for craniopharyngioma from 2000 to 2016 by the senior author. A total of 125 procedures, microsurgical (58) and endoscopic (67), were undertaken. Combined endoscopic approach was carried out in 18 of these patients, 16 children and 2 young adults. All of these patients presented with a large cystic suprasellar mass associated with hydrocephalus. In the first instance, they were treated with a transventricular endoscopic procedure to decompress the cystic component. This was followed by an endonasal transsphenoidal procedure for excision within the next 2 to 6 days. All these patients improved after the initial cyst decompression with relief of hydrocephalus while awaiting remaining tumor removal in a more elective setting. Gross total resection could be done in 84% of these patients. Diabetes insipidus was the most common postsurgical complication seen in 61% patients in the immediate period but was persistent in only two patients at 1-year follow-up. None of the children in this group developed morbid obesity. There was one case of CSF leak requiring repair after initial surgery. Peri-operative mortality was seen in one patient secondary to ventriculitis. The patients who benefit most from the combined approach are those who present with raised intracranial pressure secondary to a large tumor with cyst causing hydrocephalus. Intraventricular endoscopic cyst drainage allows resolution of hydrocephalus with restoration of normal intracranial pressure, gives time for proper preoperative work up, and has reduced incidence of CSF leak after transnasal surgery. Combined endoscopic approach thus gives a unique opportunity to remove these lesions more radically with less morbidity.

Introduction In the surgical treatment of rectal cancer, a clear circumferential resection margin and distal resection margin should be obtained. The aim of this study was to determine the morbidity, mortality, survival outcome, and local failure after total mesorectal excision (TME) in the surgical treatment of rectal cancer. Methods This retrospective study was conducted on 101 patients treated for rectal cancer using low anterior resection (LAR), abdominoperinial resection (APR), or Hartmaan’s technique. In all operative procedures, total mesorectal excisions (TMEs) were done. The patients were treated from November 2000 to April 2011 in the South Egypt Cancer Institute (SECI) of Assuit University (Egypt). Neo-adjuvant therapy was given to those patients with serosalin filtration, lymph node involvement, and sexual and urinary function impairment. Data were analyzed using IBM-SPSS version 21, and survival rates were estimated using the Kaplan-Meier method. Results One hundred one patients were evaluable (61 males, 40 females). Regarding the operative procedure used, it was: (APR), LAR, Hartmaan’s technique in 15.8%, 71.3%, and 12.9% of patients, respectively. Operation-related mortality during the 30 days after surgery was 3%. The operations resulted in morbidity in 25% of the patients, anastomotic site leak in 5.9% of the patients, urinary dysfynction in 9.9% of the patients, and erectile dysfunction in 15.8% of the male patients. Regarding safety margin, the median distances were distal/radial margin, 23/12 mm, distal limit 7 cm. Median lymph nodes harvest 19 nodes. Primary tumor locations were anteriorly 23.8%, laterally 13.9%, posteriorly 38.6%, and circumferential 23.8%. Protective stoma 16.8%. Primary Tumor TNM classification (T1, T2, T3, and T4; 3, 28.7, 55.4, and 12.9%, respectively). Nodes Metastases (N0, N1, and N2; 57.4, 31.7, and 10.9%, respectively). TNM staging (I, II, III, and IV; 15.8, 29.7, 46.5, and 7.9%, respectively). Chemotherapy was administered to 67.3% of the patients. Radiotherapy (short course neoadjuvant, long course neoadjuvant, and adjuvant postoperative used in 33.7, 20.8, and 19.8% of patients, respectively). Survival 5-years CSS was 73% and 5-years RFS 71%. Mean operative time was 213 minutes. The average amount of intraoperative blood loss was 344 mL. Conclusion Total mesorectal excision (TME) represents the gold-standard technique in rectal cancer surgery. It is safe with neoadjuvent chemoradiotherapy and provides both maximal oncological efficiency (local control and long-term survival and maintenance of a good quality of life). PMID:26816592

[Patterns and characteristics of ecological water demand in west arid zone of China--a case study of green corridor in the lower reaches of Tarim River].

Ecological water demand has some characteristics. The ecological water demand that was used for protection of the green corridor in the lower reaches of Tarim River was chiefly water demand by natural vegetation below Daxihaizi reservoir, and it included gross restoration water amount of ground water level and gross stand water amount in all over the lower reaches of Tarim River. The gross restoration water amount of ground water level mainly included restoration water amount of ground water level and lateral discharge, as well as evaporation of the course. Based on the drainage target of Alagan in 2005, gross ecological water demand was the gross water amount of restoration ground water level between Daxihaizi and Alagan, which would be 13.20 x 10(8) m3. Meanwhile, the annual average water demand would be 2.64 x 10(8) m3. Because the drainage target and vegetation protection target would be all Taitema lake in 2010, the gross ecological water demand included not only the gross water amount of restoration ground water level between Alagan and Taitema lake, but also the ecological stand water amount between Daxihaizi and Taitema lake, which would be 18.32 x 10(8) m3. Meanwhile, the annual average water demand would be 3.66 x 10(8) m3. From the year 2010 to 2030, the gross ecological water demand would be consisted of two parts (the gross stand water amount between Daxihaizi and Alagan, and the water demand by increased vegetation of 18.67 x 10(4) hm2), and the total ecological water demand during the 20 years would be 139.00 x 10(8) m3. Meanwhile, the annual average water demand would be 6.95 x 10(8) m3.

The dog was euthanized 9 months later, at which time there were distant metastases but no indication of local recurrence.

A simple method for estimating gross carbon budgets for vegetation in forest ecosystems.

PubMed

Ryan, Michael G.

1991-01-01

Gross carbon budgets for vegetation in forest ecosystems are difficult to construct because of problems in scaling flux measurements made on small samples over short periods of time and in determining belowground carbon allocation. Recently, empirical relationships have been developed to estimate total belowground carbon allocation from litterfall, and maintenance respiration from tissue nitrogen content. I outline a method for estimating gross carbon budgets using these empirical relationships together with data readily available from ecosystem studies (aboveground wood and canopy production, aboveground wood and canopy biomass, litterfall, and tissue nitrogen contents). Estimates generated with this method are compared with annual carbon fixation estimates from the Forest-BGC model for a lodgepole pine (Pinus contorta Dougl.) and a Pacific silver fir (Abies amabilis Dougl.) chronosequence.

2009-03-01

Verneuil's disease, or hidradenitis suppurativa, is a chronic suppurative disease with a tendency to sinus formation, fibrosis, and sclerosis. It is a disease of the apocrine sweat glands and may arise from each of the localizations where apocrine glands are prominent: axilla, nipples, umbilicus, perineum, groin, and buttocks. Extensive hidradenitis suppurativa of the perineal/perianal and the gluteal regions constitute a serious social problem. In this study, we present our experience with stage III extensive hidradenitis suppurativa cases, including our treatment methods and patient outcomes. A retrospective review of the medical records from January 1990 to July 2003 of 15 patients was performed. Fifteen patients underwent treatment for extensive hidradenitis suppurativa in the gluteal, perineal/perianal, and inguinal areas with total surgical excision. All patients were men (100%) and their mean age was 42.5 (range, 23-66) years. The patients underwent a total number of 21 operations. In 11 patients wounds were left open for secondary healing, and the mean time for complete wound healing in this group was 12.2 (range, 9.5-22) weeks. Two patients underwent primary wound closure by the application of rotation flaps, and their complete healing times were observed to be approximately 2 weeks. Delayed skin grafting was used for the remaining two patients in whom the wounds had been left open after the initial operation. In this group, complete wound healing took a total of 8 weeks. Only one diverting colostomy was needed in a patient in the delayed skin-grafting group. Squamous cell carcinoma was diagnosed in the specimens of one patient treated with total excision followed by the application of a rotation flap. This patient had had complaints of gluteal discharge for approximately 30 years. The cancer recurred after 6 months in the perianal region and immediate abdominoperineal resection was performed. He died during the second postoperative month due to systemic spread of the malignancy. At the end of a 5-year mean follow-up period, all remaining patients had no evidence of disease. Conservative treatment methods have little or no effect on extensive perineal/perianal hidradenitis suppurativa. Therefore, total surgical excision must be considered for these patients to prevent further complications, such as abscess, sinus tract formation, fistulization, and scarring. A temporary stoma may be needed in some cases. Because wound management after total excision is performed via different methods according to each individual patient, multidisciplinary team work is necessary and the patients often require a long hospital stay. If the treatment is not performed in an appropriate manner or if the patients are not followed closely until definitive healing, recurrence is almost inevitable. Despite the low incidence of accompanying squamous cell carcinoma, it is the most serious complication. We evaluated 15 patients to present our experience with extensive perineal/perianal and gluteal hidradenitis suppurativa.

To determine the gross and histologic configurations of the medial and lateral frontalis muscle. After making a midcoronal incision and bluntly dissecting to the orbital rim, the frontalis muscle was marked and measured. A protractor was used to measure the frontalis-orbicularis angle (FOA) and, when present, the angle of central bifurcation (AOB). Three strips of full-thickness forehead soft tissue measuring 0.5 cm × 8 cm were excised 3, 4.5, and 6 cm above the supraorbital notch and analyzed histologically for the presence of skeletal muscle fibers. Data were analyzed using 2-sample t tests, paired t tests, Pearson correlations, and mixed effect models. A p value of ≤ 0.05 was considered statistically significant. Sixty-four hemifaces of 32 cadavers (16 males) were dissected. All specimens were Caucasian. The average age was 78.2 years (range, 56-102 years). The average FOA was 88.7° (13.0°), and the average AOB was 90.0° (26.4°). A visible midline bifurcation occurred in 28 of 32 subjects (88%) at an average height of 4.7 cm (range, 2.4-7.2 cm) superior to the supraorbital notch. Continuous skeletal muscle fibers were present within the midline bifurcation histologically in 89%, 75%, and 11% of specimens 3.5, 5.0, and 6.5 cm above the supraorbital notch, respectively. In 46% of individuals, skeletal muscle fibers were continuously present microscopically within the gross bifurcation. While a medial frontalis muscle bifurcation occurs grossly in most senescent Caucasians, muscle fibers exist microscopically within this zone in nearly half of individuals.

Overuse of antibiotics is a major problem in the treatment of bovine mastitis, and antibiotic treatment is frequently non-curative, thus alternative treatments are necessary. The primary aim of this study was to evaluate the efficacy of a purified phage cocktail for treatment of bovine Staphylococcus aureus mastitis in a well-defined mouse model. Candidate phages were selected based on their in vitro performance and subsequently processed into an optimally composed phage cocktail. The highest scoring phages were further tested for efficacy and resistance suppression in broth and raw milk, with and without supplemental IgG. As these in vitro results displayed significant decreases in CFU, the cocktail was purified for testing in vivo . Lactating mice were intramammarily inoculated with S. aureus N305 (ATCC 29740), a clinical bovine mastitis isolate commonly used for experimental infection of dairy cows. The phage cocktail was applied via the same route 4 h post-inoculation. Treated mammary glands were graded for gross pathological appearance and excised for bacterial and phage load quantification as well as histopathology. Observation of gross macroscopic and histopathological changes and CFU quantification demonstrated that the phage cocktail treatment significantly improved mastitis pathology and decreased bacterial counts. Phage PFU quantification indicated that the tested phage cocktail treatment was able to maintain high intramammary phage titers without spreading systemically. The in vivo results complement the in vitro data and support our concept of phage therapy as an innovative alternative or supplementation therapy to antibiotics for the treatment of bovine mastitis.

Frontal burr hole approach for neuroendoscopic resection of craniopharyngioma with the NICO Myriad device: report of two cases.

PubMed

Moore, Reilin J; Scherer, Andrea; Fulkerson, Daniel H

2017-04-01

Craniopharyngiomas are challenging tumors to resect due to their deep location and proximity to vital structures. The perceived benefit of gross total resection may be tempered by the possibility of permanent disability. Minimally invasive techniques may reduce surgical morbidity while still allowing effective resection. The authors describe their initial experience with a neuroendoscopic transcortical, transventricular approach to two craniopharyngiomas. The surgeries were performed through a right frontal burr hole using the NICO Myriad, a side-cutting, aspiration device that fits through the working channel of a standard neuroendoscope. The imaging and medical records of two children (a 5-year-old male and a 9-year-old female) undergoing endoscopic resection of a craniopharyngioma with this technique were reviewed. Outcomes, results, and complications were noted. A gross total resection was achieved in both patients. The operative time was 180 and 143 min, respectively. The estimated blood loss was 20 and 50 cm 3 , respectively. Both patients required a cerebrospinal fluid shunt. There were no surgical complications. The NICO Myriad is an effective tool that allows a safe minimally invasive endoscopic resection of craniopharyngiomas in patients with amenable anatomy. Surgeons with experience in neuroendoscopy may be able to achieve a gross total resection of these challenging tumors through a minimally invasive burr hole approach.

The primary aims were to determine the rates of and prognostic factors for overall survival, disease-specific survival and disease-free survival following salvage total laryngectomy. Retrospective longitudinal study. Tertiary medical centres. A total of 142 patients in eastern Denmark undergoing salvage total laryngectomy for squamous cell carcinoma of the larynx or hypopharynx. 5-year overall survival, 5-year disease-specific survival, 5-year disease-free survival and prognostic factors for these outcomes. 5-year overall survival, disease-specific survival and disease-free survival were 37.7%, 54.9% and 55.3%, respectively. N classification at primary diagnosis, lymph node excision and postoperative complications within 1 year after salvage total laryngectomy were prognostic factors for shorter overall survival, disease-specific survival and disease-free survival. Residual tumour/recurrence was negatively associated with overall survival, close or involved resection margins with disease-specific survival, and second primary cancer was associated with longer disease-specific survival and disease-free survival. Nine per cent of all patients had residual tumour and 33.8% developed a recurrence. Our overall survival, disease-specific survival and disease-free survival findings are in accordance with previous studies. With the purpose of identifying recurrent tumour, we suggest extra attention being given to patients with higher N classification and need for lymph node excision during salvage total laryngectomy along with use of frozen sections. The high number of patients with recurrence within 1 year after salvage total laryngectomy occurred although thorough and regular follow-up visits were performed. © 2016 John Wiley & Sons Ltd.

New Mexico's 1998 drive-up liquor window closure. Study II: economic impact on owners.

PubMed

Lapham, Sandra C; Skipper, Betty J

2004-05-01

This study examined the economic impact of the New Mexico legislative action closing drive-up liquor windows on the retail establishments that operated them. A telephone survey was conducted 20 months after the closure seeking information and owners' opinions about how their outlets had changed since the closure and how this affected their business. In addition, 2 years of aggregated pre- and post-closure total gross receipts revenues were obtained from the New Mexico Taxation and Revenue Department, with convenience stores as a comparison group. Interviews were completed for 149 of 220 establishments. Over one-quarter of former drive-up liquor windows (28%) had been converted to 'step-in' sales, defined as an outside door where customers can stop and enter the premises while their car is running. Almost two-thirds (61%) of owners reported decreased annual gross revenues following closure, with a reported average 15% reduction in alcohol sales. This is consistent with findings of decreased gross receipts for operators of non-urban, but not urban, drive-up liquor windows compared to convenience store gross receipts. Almost three-quarters (72%) of those surveyed would re-open the drive-up window if the law were rescinded. Over one-quarter of the drive-up owners converted to step-in alcohol sales that still allow a form of drive-up liquor sales. Despite this, the forced closure of New Mexico's drive-up liquor windows negatively impacted total sales and liquor sales revenues of establishments that operated them.

The activity concentrations and distribution of natural and anthropogenic radionuclides in soils from the city of Kavadarci, Republic of Macedonia, and its environs were investigated. The purpose of the study, the first of this kind in this region was to evaluate the environmental radioactivity and radiological health hazard, as well as to determine the connection between the concentration of natural radionuclides and the geology of the terrain. A total of 45 surface soil samples were collected from evenly distributed sampling sites. Gross alpha and gross beta activity measurements were made using a gas flow proportional counter, while the activity concentrations of gamma emitting radionuclides were measured using a high purity germanium detector. The average activity concentrations of ⁴⁰K, ²²⁶Ra, ²³²Th and ¹³⁷Cs were found to be 546±118, 38.8±14.6, 43.7±18.4 and 41.5±40 Bq kg⁻¹, respectively. The mean values of gross alpha and gross beta activities were 522±192 and 681±146 Bq kg⁻¹. The mean total absorbed dose rate in air calculated from the concentration of the natural radionuclides was 67.1±20.9 nGy h⁻¹, and the corresponding annual effective dose rate outdoors was 0.082±0.026 mSv y⁻¹. The results of the analysis show strong correlation between the abundance of the natural radionuclides in soils and their geological origin.

Basal cell carcinomas (BCCs) excised leaving positive tumour margins, are at a higher risk of recurrence. Accordingly, complete tumour removal with preservation of healthy tissue, aiming for low recurrence rates, is the main goal in treating BCCs. The present study aimed to identify the reliability of the Whole Specimen Intraoperative Frozen Section Analysis (WIFSA) technique by comparing intraoperative WIFSA and postoperative Formalin-Fixed Paraffin-Embedded section analysis (FFPE) results in 1082 basal cell carcinomas and by assessing the recurrence rates during a follow-up period up to 10 years. A single-centre retrospective cohort of all patients with BCC of the face receiving surgical excision with the WIFSA method between January 2007 and December 2013 was evaluated. We compared the intraoperative frozen section results with postoperative FFPE in order to assess accuracy of the WIFSA. Recurrence rates were assessed among all BCCs with a tumour-free margin at final excision that had a minimum follow-up of 6 months. A total of 996 patients with 1082 BCCs were treated with the WIFSA. Overall agreement of WIFSA with conventional postoperative FFPE was 98·8%, sensitivity and specificity being 99·0% and 98·7% respectively. We excluded 23 BCCs that still had positive tumour margins at the end of the procedure and another 67 for the analysis of recurrence rate because follow-up was shorter than 6 months. A total of 992 BCCs with a tumour-free margin at final excision had a mean follow-up of 5·6 years (mean 67 ± 27·7 months (range 6-117 months)). The total recurrence rate was 2·1% (21 out of 992 BCCs). The recurrence rate among the primary tumours was 1·6% (13 out of 828 cases) and 4·9% among the recurring tumours (8 out of 164 cases). This study indicates that, in patients with primary or recurring BCCs, WIFSA provides a high accuracy for intraoperative specimen analysis and has a low recurrence rate after a mean follow-up of 5·6 years. This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.

To explore the effective method to treat the glottic carcinoma invading the anterior commissure, we observed the difference of three kinds of operation to the anterior commissure of dogs by semiconductor laser. Twelve dogs were divided into 3 groups at random, A: to cauterize to the thyroid cartilage's inner membrane of the anterior commissure, the right ventricular bands and vocal cord, the anterior and 1/3 of the left vocal cord; B: to cauterize part of the thyroid cartilage of the anterior commissure besides A; C: to open a window about 5 mm x 5 mm on the thyroid cartilage of the anterior commissure besides B. To take photos to observe the dogs' laryngeal wound with digital camera or electrolaryngoscope immediately, 1 week and 4 weeks, then to record the hoarseness, body weight and complications etc. All the dogs' laser surgery were completed successfully. To observe the gross specimen, it was identical between the extent of excising and the design preoperation. One week later, the neonatal membrane covered the wound incomplete. Edematization, inflammatory reaction, pseudomembrane and the hoarseness were not heavy too. No obvious complication in group A. The neonatal membrane covered the wound incomplete. Edema, inflammatory reaction, pseudomembrane and granulation can be seen in group B. Exudation was heavy in local, erosion and infected, the hoarseness was severe. No other obvious complications in C. Different extent of adhesion could be seen at the anterior commissure in group A, B and C after 4 weeks, the laryngeal web formed, and the length of vocal cord was shorter than before. The color and luster of anterior commissure membrane was normal basically, the inflammatory reaction was not heavy in A and B groups. The anterior commissural membrane appeared the dark red chronic inflammatory reaction; the window was closed by neonatal membrane completely and had no infection in group C. To observe the gross specimen: the wound of anterior commissure was covered by prosthetic epithelia completely in three groups. The window was closed by complete membrane at the anterior commissure. The No. 1- 3 dog's conditions of hoarseness in three groups after 4 weeks: slight in A group, little severe in B and C group. The change of weight was not obvious at the pre or postoperative in group A and B. No obvious complication happened in each group postoperation. The three operative methods have satisfied effects,the recovery of wound can cure well finally and no severe complications happened. It is valuable in clinic.

Transposable elements (TEs) have a significant impact on the evolution of gene function and genome structures. An endogenous nonautonomous transposable element nDart was discovered in an albino mutant that had an insertion in the Mg-protoporphyrin IX methyltransferase gene in rice. In this study, we elucidated the transposition behavior of nDart, the frequency of nDart transposition and characterized the footprint of nDart. Novel independent nDart insertions in backcrossed progenies were detected by DNA blotting analysis. In addition, germinal excision of nDart occurred at very low frequency compared with that of somatic excision, 0-13.3%, in the nDart1-4(3-2) and nDart1-A loci by a locus-specific PCR strategy. A total of 253 clones from somatic excision at five nDart loci in 10 varieties were determined. nDart rarely caused deletions beyond target site duplication (TSD). The footprint of nDart contained few transversions of nucleotides flanking to both sides of the TSD. The predominant footprint of nDart was an 8-bp addition. Precise excision of nDart was detected at a rate of only 2.2%, which occurred at two loci among the five loci examined. Furthermore, the results in this study revealed that a highly conserved mechanism of transposition is involved between maize Ac/Ds and rice Dart/nDart, which are two-component transposon systems of the hAT superfamily transposons in plant species.

To examine the most common presenting complaints of active-duty service members with isolated dorsal wrist ganglions and to determine the rate of return to unrestricted duty after open excision. Surgical records at 2 military facilities were screened to identify male and female active duty service members undergoing isolated open excision of dorsal wrist ganglions from January 1, 2006 to January 1, 2014. Electronic medical records and service disability databases were searched to identify the most common presenting symptoms and to determine whether patients returned to unrestricted active duty after surgery. Postoperative outcomes examined were pain persisting greater than 4 weeks after surgery, stiffness requiring formal occupational therapy treatment, surgical wound complications, and recurrence. A total of 125 active duty military personnel (Army, 54; Navy, 43; and Marine Corps, 28) met criteria for inclusion. Mean follow-up was 45 months. Fifteen percent (8 of 54) of the Army personnel were given permanent waivers from performing push-ups owing to persistent pain and stiffness. Pain persisting greater than 4 weeks after surgery was an independent predictor of eventual need for a permanent push-up waiver. The overall recurrence incidence was 9%. No demographic or perioperative factors were associated with recurrence. Patients whose occupation or activities require forceful wrist extension should be counseled on the considerable risk of residual pain and functional limitations that may occur after open dorsal wrist ganglion excision.

Aim of our study is to highlight the incidence and benign nature of Giant cell tumour of tendon sheath and need for complete removal, thus minimizing the chances of recurrence. A total of 26 cases of Giant cell tumour of tendon sheath operated in the department of Orthopaedics, Patna Medical College & Hospital, Patna from 2003 to 2010 were included in this study. The surgery was performed after clinical evaluation of the lesion and Fine Needle Aspiration Cytology (FNAC). The tumour underwent en bloc marginal excision. The patients were followed up for minimum two year. Our study population consisted of 18 females and 8 males. The mean age at the time of surgery was 38.3 years (range, 18-62 years). Twenty three cases were found in the 3rd and 4th decade. Twenty two cases involved upper extremity and only 4 cases in lower extremity. MRI was done in 2 cases where diagnosis was in doubt. Bony indentation on X-ray film was found in 7 cases and thorough curettage of cortical shell was done. All the cases were treated by marginal excision. Three cases developed post-operative stiffness but regained full range of movement with physiotherapy. Sensory impairment was seen in 3 cases. Recurrence occurred in 2 case and they were treated by repeat marginal excision. Meticulous en-masse marginal excision of the giant cell tumour of tendon sheath in blood less field using magnification is the treatment of choice.

Cutis verticis gyrata is a rare skin disorder characterized by formation of thick skin folds and grooves. Because of the risk of malignant transformation, these lesions must be surgically excised. In this study, the authors aimed to present a successful reconstruction of scalp with free latissimus dorsi musculocutaneous flap after total excision of giant cerebriform intradermal nevus that causes cutis verticis gyrata. An 18-year-old male patient attended to our clinic with a large tumor that covers almost 80% of his scalp. Lesion is diagnosed as cerebriform intradermal nevus. Excision of the tumor and scalp reconstruction with free latissimus dorsi musculocutaneous flap is planned and the patient is operated. Free tissue transfer is one of the best choices for full thickness defects that covers 80% of scalp with its excellent reconstructive and aesthetical results. Reconstruction with free flaps reduces the number of operations necessary to cover the defect unlike serial tissue expansion or staged excision methods. Free flaps are also a good alternative when the patient has not enough hair-bearing tissue to expand. Low donor site morbidity also makes free latissimus dorsi musculocutaneous flaps excellent choice. Cerebriform intradermal nevus is one of the most common causes of cutis verticis gyrata and has an importance due to the current risk of malign transformation. Latissimus dorsi musculocutaneous free flap is a reliable and aesthetically acceptable reconstruction option in the patients of giant cutis verticis gyrata due to sufficient pedicle length, reliable vascularized tissue volume, and large surface area.

Aims To evaluate state cigarette excise tax pass-through rates for selected price-minimizing strategies. Design Multivariate regression analysis of current smokers from a stratified, national, dual-frame telephone survey. Setting United States. Participants A total of 16 542 adult current smokers aged 18 years or older. Measurements Cigarette per pack prices paid with and without coupons were obtained for pack versus carton purchase, use of generic brands versus premium brands, and purchase from Indian reservations versus outside Indian reservations. Findings The average per pack prices paid differed substantially by price-minimizing strategy. Smokers who used any type of price-minimizing strategies paid substantially less than those who did not use these strategies (P < 0.05). Premium brand users who purchased by pack in places outside Indian reservations paid the entire amount of the excise tax, together with an additional premium of 7–10 cents per pack for every $1 increase in excise tax (pass-through rate of 1.07–1.10, P < 0.05). In contrast, carton purchasers, generic brand users or those who were likely to make their purchases on Indian reservations paid only 30–83 cents per pack for every $1 tax increase (pass-through rate of 0.30–0.83, P < 0.05). Conclusions Many smokers in the United States are able to avoid the full impact of state excise tax on cost of smoking by buying cartons, using generic brands and buying from Indian reservations.

Initial experience with endoscopic side cutting aspiration system in pure neuroendoscopic excision of large intraventricular tumors.

PubMed

Mohanty, Aaron; Thompson, Bobbye Jo; Patterson, Joel

2013-11-01

Conventionally, neuroendoscopic excision of intraventricular tumors has been difficult and time consuming because of lack of an effective decompression system that can be used through the working channel of the endoscope. The authors report their initial experience in purely endoscopic excision of large intraventricular tumors with the minimally invasive NICO Myriad system. The NICO Myriad is a side cutting soft tissue aspiration system that uses an inner reciprocating cannula and an outer stationary sheath with a side port. During decompression, applied suction approximates the tumor into the lumen of the outer sheath, with the inner cannula excising the tissue by oscillation of the cutting edge. The tumor is then removed by aspiration through the inner sheath. Three patients with large intraventricular tumors were operated by a purely endoscopic approach using a GAAB rigid endoscope and the NICO Myriad system. Of these, two had intraventricular craniopharyngiomas and one had a lateral ventricular subependymoma. The tumor size varied between 1.9 and 4.5 cm in the largest diameter. A relatively firm and solid tumor was encountered in two and a multicystic tumor with thick adherent walls in one. The tumor could be subtotally removed in one and near totally in two. There were no long-term complications. The NICO Myriad is a highly effective tumor decompression system that can be effectively used in a purely endoscopic approach to intraventricular lesions.

Olfactory neuroblastoma (ONB) is a rare malignant neuroectodermal tumor of the nasal cavity. Mixed olfactory neuroblastoma which contains areas of divergent differentiation is even rare. Till date, only 4 cases of mixed olfactory neuroblastomas have been reported. We report the case of a 46-year-old male who presented with the chief complaints of nasal bleeding and nasal obstruction since 4 months. Radiological imaging was suggestive of a large heterogeneous mass in the left superior nasal cavity with extensions into bilateral maxillary, ethmoidal, and sphenoidal sinuses, as well as into the anterior cranial fossa. Bifrontal osteoplastic craniotomy and excision of the intracranial part of the tumor from above and transnasal endoscopic removal of the mass in the nasal cavities and paranasal sinuses from below was done. Postoperative radiological imaging was suggestive of gross complete excision of the mass. Histopathological diagnosis was "mixed olfactory neuroblastoma-carcinoma (squamous and glandular differentiation) Hyams grade IV." On immunohistochemistry, the tumor cells were positive for neuron specific enolase (NSE), synaptophysin, chromogranin, and CD56 and peripherally for S100. Because of personal reasons, the patient did not take adjuvant radiotherapy. He presented again after 2 months with a full blown recurrence of esthesioneuroblastoma with similar extensions as before. The patient is now planned for salvage surgery followed by adjuvant chemoradiation. We report the 5 th case in the world of mixed olfactory neuroblastoma-carcinoma with squamous and glandular differentiation. From an analysis of the findings in the 5 reported cases of mixed olfactory neuroblastomas, one might infer that a separate subcategory of ONB, i.e., mixed ONB, should be considered because mixed ONBs have an aggressive behavior, high rates of recurrence, and these tumors should be treated aggressively by multimodality treatment.

2017-09-01

We examined the effect of a comprehensive school physical activity program (CSPAP) on gross motor skills in children. Participants were 959 children (1st-6th grade; Mean age = 9.1 ± 1.5 years; 406 girls, 553 boys) recruited from 5 low-income schools receiving a year-long CSPAP intervention. Data were collected at the beginning of the school year and at a 36-week follow-up. Gross motor skills were assessed using the Test for Gross Motor Development (3rd ed.) (TGMD-3) instrument. Multi-level mixed effects models were employed to examine the effect of CSPAP on TGMD-3 scores, testing age and sex as effect modifiers and adjusting for clustering of observations within the data structure. There were statistically significant coefficients for time (β = 8.1, 95% CI [3.9, 12.3], p < .001) and an age × time interaction (β = -1.7, 95% CI [-2.3, -1.1], p < .001) on TGMD-3 total scores. Significant improvements were also seen for locomotor skills and ball skills sub-test scores. Children showed improved gross motor skill scores at the end of the 36-week CSPAP that were modified by age, as younger children displayed greater improvements in TGMD-3 scores compared to older children.

Abrasions are the most common blunt force injuries. The precise dating of injury is extremely important in forensic medicine practice. As we know, the wound healing occurs in well-orchestrated sequence, consisting of inflammation, proliferation, and maturation.A study of occurrence of such phases will help in understanding the sequence of events in wound healing. In this context, this study of wound dating from gross and microscopic level was taken. Postmortem study of wound dating by gross and histopathological examination of abrasions was carried out in the Department of Forensic Medicine, in M.S. Ramaiah Medical College. A total of 101 abrasions were correlated to time frame the occurrence of different gross changes and microscopic changes that follow the blunt trauma. Abrasions ranging from 0 hour to a maximum of 45 days were studied. The gross changes of abrasions were in correlation with the microscopic changes; however, the role of the comorbid conditions is significant because the results showed variations with respect to healing process. This study signifies that, if naked eye examination is studied along with histopathological examination, the reliability and accuracy of dating of wound increase. Whenever accurate determination of age is required, the autopsy surgeon can subject the samples for histopathological examination and correlate before opining the age of injury.

The purpose of this study was to examine the impacts of hinged and solid anklefoot orthoses (AFOs) on standing and walking abilities in children with spastic diplegia. In a quasi-experimental design, 30 children with spastic diplegia, aged 4-6 years were recruited. They were matched in terms of age, IQ, and level of GMFCS E&R. Children were randomly assigned into 3 groups: a hinged AFO group (n=10) plus occupational therapy (OT), a solid AFO group (n=10) plus OT, a control group who used only OT for three months. Gross motor abilities were measured using Gross Motor Measure Function (GMFM). We obtained statistically significant differences in the values between baseline and after treatment in all groups. The groups were also significantly different in total GMFM after intervention. Furthermore, there were differences between hinged AFOs and solid AFOs groups, and between hinged AFOs and control groups. We concluded that gross motor function was improved in all groups; however, hinged AFOs group appears to improve the gross motor function better than solid AFOs and control groups.

Consumption of Combustible and Smokeless Tobacco - United States, 2000-2015.

Combustible and smokeless tobacco use causes adverse health outcomes, including cardiovascular disease and multiple types of cancer (1,2). Standard approaches for measuring tobacco use include self-reported surveys of use and consumption estimates based on tobacco excise tax data (3,4). To provide the most recently available tobacco consumption estimates in the United States, CDC used federal excise tax data to estimate total and per capita consumption during 2000-2015 for combustible tobacco (cigarettes, roll-your-own tobacco, pipe tobacco, small cigars, and large cigars) and smokeless tobacco (chewing tobacco and dry snuff). During this period, total combustible tobacco consumption decreased 33.5%, or 43.7% per capita. Although total cigarette consumption decreased 38.7%, cigarettes remained the most commonly used combustible tobacco product. Total noncigarette combustible tobacco (i.e., cigars, roll-your-own, and pipe tobacco) consumption increased 117.1%, or 83.8% per capita during 2000-2015. Total consumption of smokeless tobacco increased 23.1%, or 4.2% per capita. Notably, total cigarette consumption was 267.0 billion cigarettes in 2015 compared with 262.7 billion in 2014. These findings indicate that although cigarette smoking declined overall during 2000-2015, and each year from 2000 to 2014, the number of cigarettes consumed in 2015 was higher than in 2014, and the first time annual cigarette consumption was higher than the previous year since 1973. Moreover, the consumption of other combustible and smokeless tobacco products remains substantial. Implementation of proven tobacco prevention interventions (5) is warranted to further reduce tobacco use in the United States.

Uracil-DNA Glycosylase in Base Excision Repair and Adaptive Immunity

Genomic uracil is a DNA lesion but also an essential key intermediate in adaptive immunity. In B cells, activation-induced cytidine deaminase deaminates cytosine to uracil (U:G mispairs) in Ig genes to initiate antibody maturation. Uracil-DNA glycosylases (UDGs) such as uracil N-glycosylase (UNG), single strand-selective monofunctional uracil-DNA glycosylase 1 (SMUG1), and thymine-DNA glycosylase remove uracil from DNA. Gene-targeted mouse models are extensively used to investigate the role of these enzymes in DNA repair and Ig diversification. However, possible species differences in uracil processing in humans and mice are yet not established. To address this, we analyzed UDG activities and quantities in human and mouse cell lines and in splenic B cells from Ung+/+ and Ung−/− backcrossed mice. Interestingly, human cells displayed ∼15-fold higher total uracil excision capacity due to higher levels of UNG. In contrast, SMUG1 activity was ∼8-fold higher in mouse cells, constituting ∼50% of the total U:G excision activity compared with less than 1% in human cells. In activated B cells, both UNG and SMUG1 activities were at levels comparable with those measured for mouse cell lines. Moreover, SMUG1 activity per cell was not down-regulated after activation. We therefore suggest that SMUG1 may work as a weak backup activity for UNG2 during class switch recombination in Ung−/− mice. Our results reveal significant species differences in genomic uracil processing. These findings should be taken into account when mouse models are used in studies of uracil DNA repair and adaptive immunity. PMID:21454529

The aim of this study was to describe a ventral laparoscopic technique for bilateral medial iliac lymphadenectomy in dogs. Twelve intact male purpose-bred research dogs, weighing less than 15 kg, were positioned in dorsal recumbency, and a 3-portal technique was used. Bilateral dissection was performed with vessel-sealing devices while tilting the surgical table by up to 30° towards the contralateral side of the target medial iliac lymph node (MILN) without changing the surgeon’s position. Using a ventral laparoscopic approach, bilateral MILNs were identified and excised in all dogs. The mean times for unilateral and bilateral MILN dissections were 9.7 ± 3.8 and 21.0 ± 6.0 min, respectively. The mean times for the right and left MILN dissections were 10.8 ± 4.3 and 9.8 ± 2.5 min, respectively. The mean total surgery time was 43.7 ± 7.7 min. In total, 26 MILNs were dissected. Several complications, including mild to moderate capillary hemorrhage from perinodal fat and vessels (controlled laparoscopically), mild spleen trauma caused by the first trocar insertion and capsular damage of MILNs, were observed. However, there were no other major complications. All MILN samples were evaluated and deemed suitable for histopathologic diagnosis. Laparoscopic excision of MILNs is a useful method of excisional biopsy for histopathologic diagnosis. Using this ventral laparoscopic approach with the 3-portal technique, bilateral MILN dissection suitable for obtaining histopathologic samples could be achieved in a short time in dogs weighing less than 15 kg.

Total mesorectal excision (TME)--twenty years on.

PubMed

Leong, A F P K

2003-03-01

The results of total mesorectal excision (TME) for rectal cancer were first reported 20 years ago. The superior outcome in the original two papers was attributed to the complete excision of the mesorectum, preference for anterior resection over abdominoperineal resection, application of cytotoxic solutions to eradicate exfoliated tumour cells and specialisation in rectal cancer surgery. A review was conducted to examine the evidence from the literature accumulated over the past 20 years in support of this thesis. A Medline search of all studies was carried out pertaining to the issues of mesorectal metastases, anterior resection versus abdominoperineal resection, exfoliated tumour cells in rectal cancer and specialisation in rectal cancer surgery. Mesorectal metastases can be found up to 5 cm from the apparent distal edge of a rectal cancer. They occur in pT3 and pT4 tumours. Their presence indicates a poorer prognosis. There is evidence that TME improves outcomes in mid- and low-rectal cancers but its role in upper rectal and rectosigmoid cancers is controversial. It has been difficult to demonstrate the superiority of anterior resection over abdominoperineal resection as comparative studies report similar outcomes. Exfoliated tumour cells have been demonstrated to contribute to anastomotic recurrence and this probability may be reduced by the use of cytotoxic agents to irrigate the rectal stump. Multiple studies have shown that specialisation in rectal cancer surgery result in lower postoperative morbidity and mortality, local and distant recurrence rates and higher rates of sphincter saving resections. The majority of tenets espoused in the original papers on TME have found support in follow-up studies since their publication.

Angiomyofibroblastoma of the vulva: a case report of a pedunculated variant and review of the literature.

Angiomyofibroblastoma (AMF) is a benign mesenchymal tumor usually found in the vulva. We reviewed 70 cases of vulvar AMF that have been reported in the English-language literature and report 1 case of a pedunculated variant. Our case brings the total reported to 71 and is only the fourth pedunculated variant reported. This 50-year-old woman presented to our gynecology clinic with a 1-year history of a left labial mass. It began as pea-sized, and rapidly grew to 12 cm in diameter. Physical examination demonstrated a 12-cm pedunculated soft mass arising from the left labia majora. The clinical diagnosis was aggressive angiomyxoma, and a simple excision was performed. The final pathology demonstrated AMF. The patient remains free from tumor at 4 years of follow-up. Seventy-one cases were summarized. The mean age at presentation was 45 years. The lesions were equally distributed between the left (52%) and right (48%). The most common clinical diagnosis was a Bartholin gland cyst (46%) or lipoma (15%). The mean duration of the lesion before seeking treatment was 29 months, and the mean diameter at presentation was 5.9 cm. All of the patients were treated with simple excision. The mean duration of follow-up was 37 months. There was 1 report of sarcomatous transformation 2 years after initial treatment. Angiomyofibroblastoma is a rare benign tumor that most often occurs in the vulva. Differential diagnosis may include aggressive angiomyxoma, Bartholin cyst, or lipoma. The treatment of choice is simple total excision, which is usually curative.

2017-07-25

Total mesorectal excision (TME) is a mile-stone procedure in the history of rectal cancer surgery, but the exposure of surgical field of distal rectum is usually poor in patients with male, obese and narrow pelvis, which may lead to tumor residue and relative complications. Recently, a new technique called transanal TME (taTME) is considered to solve the above problems, but most medical centers are still in the learning curve of this procedure. Therefore, anatomical planes and landmarks of taTME for rectal cancer and prophylaxis of intraoperative complications are induced in this paper, which includes posterior plane: angle of anus and distal mesorectum and bleeding of mesorectum; rectosacral fascia and presacral bleeding; lateral and posterior-lateral plane: posterior branches of pelvic plexus and damage of anal function; anterior plane: vessel branches of neurovascular bundle and bleeding. Familiarity with the specific anatomical planes and landmarks plays an important role in shortening the learning curve, decreasing the complications, increasing the success rate of operation and standardization of taTME.

Evaluation of protocol change in burn-care management using the Cox proportional hazards model with time-dependent covariates.

Survival analysis methods are valuable for detecting intervention effects because detailed information from patient records and sensitive outcome measures are used. The burn unit at a large university hospital replaced routine bathing with total body bathing using chlorhexidine gluconate for antimicrobial effect. A Cox proportional hazards model was used to analyse time from admission until either infection with Staphylococcus aureus or discharge for 155 patients, controlling for burn severity and two time-dependent covariates: days until first wound excision and days until first administration of prophylactic antibiotics. The risk of infection was 55 per cent higher in the historical control group, although not statistically significant. There was also some indication that early wound excision may be important as an infection-control measure for burn patients.

Although the number of excised lymph nodes (LNs) represents a quality assurance measure in lymphadenectomy for many solid tumors, the minimum number of LNs to be dissected has not been established for melanoma. To investigate the distribution of the number of excised LNs in a large patient series (N = 2526) to identify values that may serve as benchmarks for monitoring the quality of lymphadenectomy in patients with melanoma. A retrospective multicenter study was conducted (1992-2010) in tertiary referral centers for treatment of cutaneous melanoma. Medical records on 2526 patients who underwent lymphadenectomy for regional LN metastasis associated with cutaneous melanoma were examined. Patients had undergone lymphadenectomy for regional LN metastasis. The mean, median, and 10th percentile of the number of excised LNs were calculated for the axilla (3 levels), neck (≤3 or ≥4 dissected levels), inguinal, and ilioinguinal LN fields. After 3-level axillary (n = 1150), 3-level or less neck (n = 77), 4-level or more neck (n = 135), inguinal (n = 209), and ilioinguinal (n = 955) dissections, the median (interquartile range [IQR]) and mean (SD) number of excised LNs were as follows: 3-level axillary dissection, 20 (15-27) and 22 (8); 3-level or less neck, 21 (14-33) and 24 (15); 4-level or more neck, 29 (21-41) and 31 (14); inguinal, 11 ( 9-14) and 12 (5); and ilioinguinal, 21 (16-26) and 22 (4). A total of 90% of the patients had 12, 7, 14, 6, and 13 excised LNs (10th percentile of the distribution) after 3-level axillary, 3-level or less neck, 4-level or more neck, inguinal, and ilioinguinal dissections, respectively. More excised LNs were detected in younger (21 for those <54 years of age and 19 for ≥54 years, P < .001) and male (21 for male sex and 19 for female sex, P < .001) patients from high-volume institutions (21 for volume of ≥300 vs 18 for volume <300, P < .001) with a more recent year of diagnosis (21 for years 2002-2010 vs 18 for years 1992-2001, P < .001), LN micrometastasis vs macrometastasis (20 vs 19, P = .005), and more positive LNs (R² = 0.03, P < .001); however, the differences between median values were small. These minimum numbers of excised LNs are reproducible across the institution, patient, and tumor factors evaluated. They can be taken into consideration when monitoring the quality of lymphadenectomy in melanoma and can represent entry criteria for randomized trials investigating adjuvant therapies.

To compare efficacy of a web-based multimodal training programme, 'Move it to improve it' (Mitii TM ), to usual care on gross motor capacity and performance for children with an acquired brain injury. Randomized waitlist controlled trial. Home environment. A total of 60 independently ambulant children (30 in each group), minimum 12 months post-acquired brain injury were recruited and randomly allocated to receive either 20 weeks of Mitii TM training (30 minutes/day, six days/week, total 60 hours) immediately, or waitlisted (usual care control group) for 20 weeks. A total of 58 children completed baseline assessments (32 males; age 11 years 11 months ± 2 years 6 months; Gross Motor Function Classification System equivalent I = 29, II = 29). The Mitii TM program comprised of gross motor, upper limb and visual perception/cognitive activities. The primary outcome was 30-second, repetition maximum functional strength tests for the lower limb (sit-to-stand, step-ups, half-kneel to stand). Secondary outcomes were the 6-minute walk test, High-level Mobility Assessment Tool, Timed Up and Go Test and habitual physical activity as captured by four-day accelerometry. Groups were equivalent at baseline on demographic and clinical measures. The Mitii TM group demonstrated significantly greater improvements on combined score of functional strength tests (mean difference 10.19 repetitions; 95% confidence interval, 3.26-17.11; p = 0.006) compared with the control group. There were no other between-group differences on secondary outcomes. Although the Mitii TM programme demonstrated statistically significant improvements in the functional strength tests of the lower limb, results did not exceed the minimum detectable change and cannot be considered clinically relevant for children with an acquired brain injury.

The role of research in the failure of the alcopops excise in Australia: what have we learned?

PubMed

Shakeshaft, Anthony; Doran, Christopher M; Byrnes, Joshua

2009-08-17

We believe that a lack of adequate alcohol measures research is partly responsible for the failure of the Australian Government to pass legislation to equalise the excise applied to straight spirits and premixed spirits ("alcopops"). Current measures only assess total alcohol consumption rather than patterns of consumption, and do not adequately identify alcohol-related harm at a population level. Possible solutions include making further efforts to develop applied community-level measures and responding to the repeated calls for national collection and analysis of alcohol sales data. With the Australian Government able to retain the alcopops excise raised to date, there is a unique opportunity for greater collaboration between researchers and government to ensure high-quality and publicly relevant research is funded and conducted to address the current lack of adequate measures research. Measures research is a priority, as this is the basis for increasing the accuracy of data with which more cost-effective public policy and initiatives can be formulated and evaluated. The challenge is for researchers and the Australian Government to align their expertise to ensure revenue from public taxes engenders measurable public health benefit.

Hookwire localization is the current standard technique for radiological marking of nonpalpable breast lesions. Stereotactic directional vacuum-assisted breast biopsy (SVAB) is of sufficient sensitivity and specificity to replace surgical biopsy. Wire localization for metallic marker clips placed after SVAB is needed. To describe a method for performing computed tomography (CT)-guided hookwire localization using a radial approach for metallic marker clips placed percutaneously after SVAB. Nineteen women scheduled for SVAB with marker-clip placement, CT-guided wire localization of marker clips, and, eventually, surgical excision were prospectively entered into the study. CT-guided wire localization was performed with a radial approach, followed by placement of a localizing marker-clip surgical excision. Feasibility and reliability of the procedure and the incidence of complications were examined. CT-guided wire localization surgical excision was successfully performed in all 19 women without any complications. The mean total procedure time was 15 min. The median distance on CT image from marker clip to hookwire was 2 mm (range 0-3 mm). CT-guided preoperative hookwire localization with a radial approach for marker clips after SVAB is technically feasible.

A method of burn treatment (immunosuppression and temporary skin transplantation) for patients suffering from massive third degree burns is evaluated. The method is based on the prompt excision of all dead tissue (burn eschar) and immediate closure of the wound by skin grafts. Total wound closure is achieved before bacterial infection or organ failure takes place by carrying out all initial excision and grafting procedures within the first ten days post burn and supplementing the limited amount of autograft with allograft. Continuous wound closure is maintained for up to 50 days through immunosuppression. Both azathioprine and ATG have been used but ATG is preferred. During the period of immunosuppression, allograft is stepwise excised and replaced with autograft donor sites regenerate for recropping. Bacterial complications are minimized by housing the patient in the protected environment of the Bacteria Controlled Nursing Unit. Intensive protein and calorie alimentation are provided, and 0.5% aqueous AgNO3 dressings are used. A swinging febrile illness has been associated with large areas of allograft rejection. Eleven children have been treated and seven have been returned to normal, productive schooling. Images Fig. 1. Fig. 2. Fig. 3. Fig. 4. PMID:809014

Relationship Between Broiler Body Weights, Eimeria maxima Gross Lesion Scores, and Microscores in Three Anticoccidial Sensitivity Tests.

PubMed

Barrios, Miguel A; Da Costa, Manuel; Kimminau, Emily; Fuller, Lorraine; Clark, Steven; Pesti, Gene; Beckstead, Robert

2017-06-01

Anticoccidial sensitivity tests (ASTs) serve to determine the efficacy of anticoccidial drugs against Eimeria field isolates in a controlled laboratory setting. The most commonly measured parameters are body weight gain, feed conversion ratio, gross intestinal lesion scores, and mortality. Due to the difficulty in reliably scoring gross lesion scores of Eimeria maxima , microscopic analysis of intestinal scrapings (microscores) can be used in the field to indicate the presence of this particular Eimeria. The goal of this study was to determine the relationship between E. maxima microscores and broiler body weights and gross E. maxima lesion scores in three ASTs. Day-old broiler chicks were raised for 12 days on a standard corn-soy diet. On Day 12, chicks were placed in Petersime batteries and treatment diets were provided. There were six birds per pen, four pens per treatment, and 12 treatments, for a total of 288 chicks per AST. The treatments were as follows: 1) nonmedicated, noninfected; 2) nonmedicated, infected; 3) lasalocid, infected; 4) salinomycin, infected; 5) diclazuril, infected; 6) monensin, infected; 7) decoquinate, infected; 8) narasin + nicarbazin, infected; 9) narasin, infected; 10) nicarbazin, infected; 11) robenidine, infected; and 12) zoalene, infected. On Day 14, chicks were challenged with an Eimeria field isolate by oral gavage. On Day 20, broilers were weighed, and gross lesion scores and microscores were classified from 0 to 4 depending on the severity of the gross lesion scores and E. maxima microscores. Data from three trials using different field isolates were statistically analyzed using a logarithmic regression model. There was no relationship (P = 0.1224) between microscores and body weight gain. There was a positive relationship between microscores and gross lesion scores (P = 0.004). However, there was also an interaction between isolate and treatment (P < 0.0001). Lastly, the interaction between isolate and gross lesion scores (P = 0.0041) demonstrates that the significance of the relationship between microscores and gross lesion scores may be dependent on pathogenicity of the challenge Eimeria or the amount of E. maxima in the inoculum.

Craniopagus twins: surgical anatomy and embryology and their implications.

PubMed Central

O'Connell, J E

1976-01-01

Craniopagus is of two types, partial and total. In the partial form the union is of limited extent, particularly as regards its depth, and separation can be expected to be followed by the survival of both children to lead normal lives. In the total form, of which three varieties can be recognized, the two brains can be regarded as lying within a single cranium and a series of gross intracranial abnormalities develops. These include deformity of the skull base, deformity and displacement of the cerebrum, and a gross circulatory abnormality. It is considered that these and other abnormalities, unlike the primary defect, which is defined, are secondary ones; explanations for them, based on anatomy and embryology, are put forward. The implications of the various anomalies are discussed and the ethical aspects of attempted separation in these major unions considered. Images PMID:1255206

Expanded Endonasal Endoscopic Approach for Resection of an Infrasellar Craniopharyngioma.

PubMed

Abou-Al-Shaar, Hussam; Blitz, Ari M; Rodriguez, Fausto J; Ishii, Masaru; Gallia, Gary L

2016-11-01

Craniopharyngiomas are uncommon benign locally aggressive epithelial tumors mostly located in the sellar and suprasellar regions. An infrasellar origin of these tumors is rare. The authors report a 22-year-old male patient with a purely infrasellar adamantinomatous craniopharyngioma centered in the nasopharynx with extension into the posterior nasal septum, sphenoid sinus, and clivus. Gross total resection was achieved using an expanded endonasal endoscopic transethmoidal, transsphenoidal, transpterygoid, and transclival approach. Follow-up at one year demonstrated no evidence of disease recurrence. Infrasellar craniopharyngioma should be included in the differential diagnosis of sinonasal masses even in the absence of sellar extension. Expanded endonasal endoscopic approaches provide excellent access to and visualization of such lesions and may obviate the need for postoperative radiotherapy when gross total resection is achieved.

Phosphaturic mesenchymal tumor of the brain without tumor-induced osteomalacia in an 8-year-old girl: case report.

PubMed

2016-05-01

Phosphaturic mesenchymal tumor (mixed connective tissue variant) (PMT-MCT) are tumors that may cause tumor-induced osteomalacia and rarely appear intracranially. The authors describe the case of an 8-year-old girl who was found to have PMT-MCT with involvement of the cerebellar hemisphere and a small tumor pedicle breaching the dura mater and involving the skull. This was removed surgically in gross-total fashion without further complication. Histologically the tumor was confirmed to be a PMT-MCT. There was no evidence of tumor-induced osteomalacia. At the 42-month follow-up, the patient is doing well, has no abnormalities, and is free of recurrence. PMT-MCTs are rare tumors that may involve the brain parenchyma. A gross-total resection may be effective to cure these lesions.

Primary cardiac sarcomas, although rare, are aggressive and lethal, requiring thorough surgical resection and adjuvant chemotherapy for the best possible outcome. We report the case of a 32-year-old woman who underwent total artificial heart implantation for right-sided heart failure caused by right ventricular angiosarcoma. For the first several weeks in intensive care, the patient recovered uneventfully. However, a postoperative liver biopsy indicated hepatocellular injury consistent with preoperative chemotherapy. She developed continuing liver failure, from which she died despite good cardiac function.

To evaluate CO2 laser excision, vaporization and combined techniques for treatment of vulvar intraepithelial neoplasia (VIN). Thirty-nine cases of VIN 3, 15 cases of VIN 2 and 9 of VIN 1, for a total of 63 patients with histologically proven VIN, underwent laser excision or vaporization under colposcopic guidance, using local anesthesia, in an outpatient setting or after day-surgery admission. Clinical aspects, cervical intraepithelial neoplasia (CIN) and vaginal intraepithelial neoplasia (VaIN) association, types of CO2 laser treatment, follow-up, recurrences and second treatments were evaluated. Twenty-seven (41.3%) patients underwent laser vaporization, and 37 (58.7%) with VIN 3, underwent laser excision or the combined technique. Colposcopic and biopsy examinations of patients with VIN revealed three cases of CIN 3 and nine cases of VaIN 3; two patients had concomitant VIN 3, CIN 3 and VaIN 3. Local anesthesia, using 2% carbocaine, and outpatient or day-surgery treatments were possible in all cases. A small incidence of intraoperative complications (4.8%) and absence of postoperative complications were observed. A single session was curative in 76.9% of patients treated with laser vaporization and in 78.4% of those treated with laser excision. Eleven cases of recurrent VIN and two cases of invasive vulvar carcinoma were observed during follow-up. A second laser procedure was carred out in all cases of relapsed VIN, with an overall cure rate of 96.8% after two treatments. Radical vulvectomy associated with inguinal-femoral lymphadenectomy was performed in the two cases of invasive carcinoma. CO2 laser surgery permits treatment of VIN in an outpatient or day-surgery setting under local anesthesia with excellent cosmetic and functional results. The treatment can also be adjusted to the patient's specific needs, with the possibility of calibrating the depth of the vaporized and removed tissues. Excisional treatment is the preferred method because it permits histologic evaluation of the excised tissue and detection of possible occult early invasion.

The Productivity and Technical Efficiency of Textile Industry Clusters in India

NASA Astrophysics Data System (ADS)

Bhaskaran, E.

2013-09-01

The Indian textile industry is one the largest and oldest sectors in the country and among the most important in the economy in terms of output, investment and employment (E). The sector employs nearly 35 million people and after agriculture, is the second-highest employer in the country. Its importance is underlined by the fact that it accounts for around 4 % of Gross Domestic Product, 14 % of industrial production, 9 % of excise collections, 18 % of E in the industrial sector, and 16 % of the country's total exports (Ex) earnings. For inclusive growth and sustainable development most of the Textile Manufacturers has adopted the Cluster Development Approach. The objective is to study the physical and financial performance, correlation, regression and Data Envelopment Analysis by measuring technical efficiency (Ø), peer weights (λi), input slacks (S-), output slacks (S+) and return to scale of four textile clusters (TCs) namely IchalKaranji Textile Cluster, Maharashtra; Ludhiana Textile Cluster, Punjab; Tirupur Textile Cluster, Tamilnadu and Panipat Textile Cluster, Haryana in India. The methodology adopted is using Data Envelopment Analysis of Output Oriented Banker Charnes Cooper Model by taking number of units (U) and number of E as inputs and sales (S) and Ex in crores as an outputs. The non-zero λi's represents the weights for efficient clusters. The S > 0 obtained for one TC reveals the excess U (S-) and E (S-) and shortage in sales (S+) and Ex (S+). To conclude, for inclusive growth and sustainable development, the inefficient TC should increase their S/turnover and Ex, as decrease in number of enterprises and E is practically not possible. Moreover for sustainable development, the TC should strengthen infrastructure interrelationships, technology interrelationships, procurement interrelationships, production interrelationships and marketing interrelationships to decrease cost, increase productivity and efficiency to compete in the world market.

Estimates of the economic contributions of the bidi manufacturing industry in India.

Bidis, the most common smoking tobacco product in India, remain largely untaxed and are subject to very few regulations to discourage their use. A major argument against tax increases is the large potential loss of economic activity and employment in the bidi industry from reduced consumption. We used a nationally representative survey of unorganised bidi manufacturing firms (n=2841) in India to estimate the economic contribution of the industry. We find that of the 35 states and union territories of India, the bidi industry operated across 17 states, with over 95% of its production concentrated in 10 states. Bidi manufacturing firms contributed 0.50% of total sales and 0.6% of the gross value added by the manufacturing economy in 2005-2006. The industry employed approximately 3.4 million full-time workers, which comprise about 0.7% of employment in all sectors. A further 0.7 million were part-time workers. Bidi workers were also among the lowest paid employees in India. The industry offered only 0.09% of all compensation provided in the manufacturing sector (organised and unorganised). Considering the relatively small economic footprint of the bidi industry in India, higher excise taxes and regulations on bidis are unlikely to disrupt economic growth at an aggregate level, or lead to mass unemployment and economic hardship among small bidi workers. On average, the economic annual output per bidi worker is about US$143, which is an order of magnitude smaller than the large economic losses from the several hundred thousand deaths due to bidi smoking per year.

The role of three-dimensional pure bovine gelatin scaffolds in tendon healing, modeling, and remodeling: an in vivo investigation with potential clinical value.

PubMed

Oryan, Ahmad; Sharifi, Pardis; Moshiri, Ali; Silver, Ian A

2017-09-01

Large tendon defects involving extensive tissue loss present complex clinical problems. Surgical reconstruction of such injuries is normally performed by transplanting autogenous and allogenous soft tissues that are expected to remodel to mimic a normal tendon. However, the use of grafts has always been associated with significant limitations. Tissue engineering employing artificial scaffolds may provide acceptable alternatives. Gelatin is a hydrolyzed form of collagen that is bioactive, biodegradable, and biocompatible. The present study has investigated the suitability of gelatin scaffold for promoting healing of a large tendon-defect model in rabbits. An experimental model of a large tendon defect was produced by partial excision of the Achilles tendon of the left hind leg in adult rabbits. To standardize and stabilize the length of the tendon defect a modified Kessler core suture was anchored in the sectioned tendon ends. The defects were either left untreated or filled with three-dimensional gelatin scaffold. Before euthanasia 60 days after injury, the progress of healing was evaluated clinically. Samples of healing tendon were harvested at autopsy and evaluated by gross, histopathologic, scanning, and transmission electron microscopy, and by biomechanical testing. The treated animals showed superior weight-bearing and physical activity compared with those untreated, while frequency of peritendinous adhesions around the healing site was reduced. The gelatin scaffold itself was totally degraded and replaced by neo-tendon that morphologically had significantly greater numbers, diameters, density, and maturation of collagen fibrils, fibers, and fiber bundles than untreated tendon scar tissue. It also had mechanically higher ultimate load, yield load, stiffness, maximum stress and elastic modulus, when compared to the untreated tendons. Gelatin scaffold may be a valuable option in surgical reconstruction of large tendon defects.

Endoscopic endonasal surgery for benign fibro-osseous lesions of the pediatric skull base.

2015-09-01

To describe the presentation, treatment, and outcomes of benign fibro-osseous tumors involving the skull base in a pediatric population. Retrospective chart review from January 2002 to September 2013 of pediatric patients (ages 0-18 years) who underwent endoscopic endonasal surgery (EES) for benign fibro-osseous tumors involving the skull base. Fourteen patients were identified with an age range of 2.7 to 17.9 years (mean, 12.5 years). Six juvenile ossifying fibromas, five benign fibro-osseous lesions, two osteomas, and one fibrous dysplasia were treated. Ocular symptoms and nasal obstruction were the most common presenting symptoms in nine (64%) and six (43%) of patients, respectively; five (36%) presented with proptosis and four (29%) with diplopia. Two (14%) patients had cranial nerve VI palsy. Transsellar and transclival approaches were used in five (36%) of patients. Orbital and optic nerve decompressions were the most common components of the approaches performed in nine (64%) of the surgeries. Gross total resection (GTR) was achieved with single-stage surgery in 10 (71%) patients; two additional patients underwent staged GTR. Two intraoperative cerebrospinal fluid (CSF) leaks occurred and were repaired endoscopically. There were no postoperative CSF leaks or infectious complications. Two patients had transient diplopia, and two had transient diabetes insipidus, all of which resolved. The mean follow-up was 13.8 months. Two patients had a recurrence, and both required additional EES achieving GTR. EES for benign fibro-osseous tumors of the skull base is a safe and effective treatment for excision of these lesions in the pediatric population. 4. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

Lateral talar process fragment excision may be followed by hindfoot instability and altered biomechanics. There is controversy regarding the ideal fragment size for internal fixation versus excision and a concern that excision of a large fragment may lead to significant instability. The aim of this study was to assess the effect of a simulated large lateral talar process excision on ankle and subtalar joint stability.A custom-made seesaw rig was designed to apply inversion/eversion stress loading on 7 fresh-frozen human cadaveric lower legs and investigate them in pre-excision, 5 cm and 10 cm lateral talar process fragment excision states. Anteroposterior radiographs were taken to assess ankle and subtalar joint tilt and calculate angular change from neutral hindfoot alignment to 10-kg forced inversion/eversion. Ankle joint pressures and contact areas were measured under 30-kg axial load in neutral hindfoot alignment.In comparison to the pre-excision state, no significantly different mediolateral angular change was observed in the subtalar joint after 5 and 10 cm lateral talar process fragment excision in inversion and eversion. With respect to the ankle joint, 10-cm fragment excision produced significantly bigger inversion tibiotalar tilt compared with the pre-excision state, P = .04. No significant change of the ankle joint pressure and contact area was detected after 5 and 10-cm excision in comparison with the pre-excison state.An excision of up to 10 cm of the lateral talar process does not cause a significant instability at the level of the subtalar joint but might be a destabilizing factor at the ankle joint under inversion stress. The latter could be related to extensive soft tissue dissection required for resection.

A simulation model to predict the fiscal and public health impact of a change in cigarette excise taxes.

PubMed

van Walbeek, Corné

2010-02-01

(1) To present a model that predicts changes in cigarette consumption and excise revenue in response to excise tax changes, and (2) to demonstrate that, if the industry has market power, increases in specific taxes have better tobacco control consequences than increases in ad valorem taxes. All model parameters are user-determined. The model calculates likely changes in cigarette consumption, smoking prevalence and excise tax revenues due to an excise tax change. The model is applicable to countries that levy excise tax as specific or ad valorem taxes. For a representative low-income or middle-income country a 20% excise tax increase decreases cigarette consumption and industry revenue by 5% and increases excise tax revenues by 14%, if there is no change in the net-of-tax price. If the excise tax is levied as a specific tax, the industry has an incentive to raise the net-of-tax price, enhancing the consumption-reducing impact of the tax increase. If the excise tax is levied as an ad valorem tax, the industry has no such incentive. The industry has an incentive to reduce the net-of-tax price in response to an ad valorem excise tax increase, undermining the public health and fiscal benefits of the tax increase. This paper presents a simple web-based tool that allows policy makers and tobacco control advocates to estimate the likely consumption, fiscal and mortality impacts of a change in the cigarette excise tax. If a country wishes to reduce cigarette consumption by increasing the excise tax, a specific tax structure is better than an ad valorem tax structure.

The Fars province is located in the south-west region of Iran where different nuclear sites has been established, such as Bushehr Nuclear Power Plant. In this research, 92 water samples from the water supplies of Shiraz city and springs of the Fars province were investigated with regard to the concentrations of natural radioactive elements, total uranium, (226)Ra, gross alpha and gross beta. (226)Ra concentration was determined by the (222)Rn emanation method. To measure the total uranium concentration, a laser fluorimetry analyzer (UA-3) was used. The mean concentration of (226)Ra in Shiraz's water resources was 23.9 mBq l(-1), while 93 % of spring waters have a concentration <2 mBq l(-1). The results of uranium concentration measurements show the mean concentrations of 7.6 and 6 μg l(-1) in the water of Shiraz and springs of Fars, respectively. The gross alpha and beta concentrations measured by the evaporation method were lower than the limit of detection of the measuring instruments used in this survey. The mean annual effective doses of infants, children and adults from (238)U and (226)Ra content of Shiraz's water and spring waters were estimated. According to the results of this study, the activity concentration in water samples were below the maximum permissible concentrations determined by the World Health Organization and the US Environmental Protection Agency. Finally, the correlation between (226)Ra and total U activity concentrations and geochemical properties of water samples, i.e. pH, total dissolve solids and SO4(-2), were estimated.

The values for strontium-90 and gross beta activity in the fat and non- fat fractions from the livers of twelve coconut crabs (Birgus latro) collected at Rongelap Atoll during March 1958 are presented. Although fat constituted an average of 47 percent by weight on a wet weight basis (74 percent on a dry weight basis), gross beta activity of the fat fraction amounted to less than 0.5 percent of the total activity on a wet weight basis. Fat content on a wet weight basis had a range of 31 percent to 65 percent. There is a linear relationship between strontium-90more » activity and gross beta activity. Since the fat content of coconut crab liver is variable and the fat fraction contains practically no radioactivity, it is suggested that the radioactivity (and mineral content) of liver samples be compared on the basis of the non-fat solids.

Introduction Abrasions are the most common blunt force injuries. The precise dating of injury is extremely important in forensic medicine practice. As we know, the wound healing occurs in well-orchestrated sequence, consisting of inflammation, proliferation, and maturation. A study of occurrence of such phases will help in understanding the sequence of events in wound healing. In this context, this study of wound dating from gross and microscopic level was taken. Materials and Methods Postmortem study of wound dating by gross and histopathological examination of abrasions was carried out in the Department of Forensic Medicine, in M.S. Ramaiah Medical College. A total of 101 abrasions were correlated to time frame the occurrence of different gross changes and microscopic changes that follow the blunt trauma. Abrasions ranging from 0 hour to a maximum of 45 days were studied. Results The gross changes of abrasions were in correlation with the microscopic changes; however, the role of the comorbid conditions is significant because the results showed variations with respect to healing process. Conclusions This study signifies that, if naked eye examination is studied along with histopathological examination, the reliability and accuracy of dating of wound increase. Whenever accurate determination of age is required, the autopsy surgeon can subject the samples for histopathological examination and correlate before opining the age of injury. PMID:28418938

To examine the relationship between reflection, gender, residency choice, word count, and academic achievement among medical students. A modified version of the Reflection Evaluation for Learners' Enhanced Competencies Tool (REFLECT) was developed and used for this study (Cronbach's alpha of 0.86 with an intraclass correlation coefficient [ICC] of 0.68). This was applied to writing samples about professionalism in gross anatomy from first-year medical students between 2005 and 2011. Four analysts reviewed and scored written reflections independently. Composite reflection scores were compared with gender, residency choice, length of written reflection, NBME® Gross Anatomy and Embryology Subject Examination scores, and final gross anatomy course. Total of 319 written reflections were evaluated. Female students who pursued medicine specialties had the highest composite reflection scores (87 [27.2%]). Word count frequently correlated with reflection score (p < 0.0001). Students who performed well on the NBME® Gross Anatomy and Embryology Subject Examination tended to achieve high anatomy course grades (p < 0.0001). There was no statistically significant relationship between composite reflection scores and NBME® Gross Anatomy and Embryology Subject Examination scores (p = 0.16) or anatomy course grades (p = 0.90). This study suggests there are likely no correlations between reflective capacity and academic performance on tests of medical knowledge administered early in the medical curriculum.

To evaluate state cigarette excise tax pass-through rates for selected price-minimizing strategies. Multivariate regression analysis of current smokers from a stratified, national, dual-frame telephone survey. United States. A total of 16 542 adult current smokers aged 18 years or older. Cigarette per pack prices paid with and without coupons were obtained for pack versus carton purchase, use of generic brands versus premium brands, and purchase from Indian reservations versus outside Indian reservations. The average per pack prices paid differed substantially by price-minimizing strategy. Smokers who used any type of price-minimizing strategies paid substantially less than those who did not use these strategies (P < 0.05). Premium brand users who purchased by pack in places outside Indian reservations paid the entire amount of the excise tax, together with an additional premium of 7-10 cents per pack for every $1 increase in excise tax (pass-through rate of 1.07-1.10, P < 0.05). In contrast, carton purchasers, generic brand users or those who were likely to make their purchases on Indian reservations paid only 30-83 cents per pack for every $1 tax increase (pass-through rate of 0.30-0.83, P < 0.05). Many smokers in the United States are able to avoid the full impact of state excise tax on cost of smoking by buying cartons, using generic brands and buying from Indian reservations. Published 2014.

to determine the frequency of malignancy in subsequent breast excisions following core-needle biopsy (CNB) diagnosis of pure flat epithelial atypia (pFEA) and to evaluate the imaging features of the associated tumors. Retrospective review of 8,996 image-guided CNB (2002-2010) identified 115 cases of FEA not associated with other atypia. Patients with history of breast cancer or radiation therapy were excluded. One hundred four cases (women) with pFEA (mean age 51 years, range 29-77 years) were reviewed. Stereotactic CNB was performed in 79 (76%) cases and ultrasound (US)-guided CNB in 25 (24%) cases. In 99 cases 14G needles were used, and 10G vacuum-assisted devices were used in 5 cases. Ninety-four patients had subsequent excision. Ten patients declined excision, and imaging follow-up (mean of 36 months) is available. The upgrade rate of pFEA was defined as the number of patients diagnosed with invasive carcinoma (IC) or carcinoma in situ (CIS) divided by the total number of patients. 10 of 104 (9.6%) patients were diagnosed with cancer: 9 presented as calcifications (89% fine pleomorphic and amorphous) and 1 case as a mammographically occult mass. The size of calcifications was not statistically significant (P=0.358). Five cases had ductal carcinoma in situ (DCIS) and five cases had IC (ductal and lobular) presenting as amorphous and pleomorphic calcifications. The upgrade rate of pFEA in our series was 9.6%. The presence of 4.8% of invasive cancers is substantial and warrants continuing management with surgical excision in all cases.

To describe the surgical management of second branchial fistulae that extend to the pharynx, specifically to determine whether tonsillectomy, along with surgical excision of the tract affects the rate of recurrence. Retrospective chart review of pediatric patients (age<18) who underwent surgical excision of second branchial anomalies at a tertiary-care children's hospital between January 1, 2006 and September 1, 2011. Sinus tracts that extended to the pharynx were considered to be fistulae. Seventy-four patients were identified who underwent surgical excision of 85 total second branchial anomalies - 20 cysts (23.5%), 29 sinuses (34.1%), and 36 fistulae (42.4%). The 36 fistulae were removed from 32 patients, 23 males and 9 females, with an average age of 43.3 months. There were 16 right, 11 left, and 5 bilateral lesions. In 14 (43.8%) of the fistulae cases, a tonsillectomy was performed. There was only one recurrence (2.8%), which occurred 41 months postoperatively. No statistically significant difference for recurrence (p=1.0) was found between the group of patients that underwent tonsillectomy and those that did not. Pediatric branchial anomalies can present as a cyst, sinus, or fistula. They are developmental failures in the involution of the branchial apparatus during the embryologic period. Management of second branchial anomalies is with surgical excision of the tract and ligation of the terminal attachment to the pharynx. Our results suggest that the recurrence rates are not affected by whether or not an ipsilateral tonsillectomy is performed. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

The study attempts to estimate the demand for cigarettes in Tanzania and presents simulation results on the effect of the cigarette excise tax on smoking participation, government revenue, and related topics. After briefly summarizing the magnitude and spread of cigarette consumption in the country, the paper reviews some empirical estimates from African and other countries. The 2008 Tanzanian household budget survey was used to estimate the demand for cigarettes in Tanzania. The descriptive statistics suggest that the smoking prevalence for Tanzania is 15.35 percent with low variability across expenditure (income) groups. Smoking intensity and per capita consumption were estimated at 7.08 cigarettes and 1.33 cigarettes, respectively, a relatively low value. A two-part demand equation model was used to estimate various elasticities. For the overall equation, the price elasticities of smoking participation, smoking intensity, and total elasticity were estimated at −0.879, −0.853, and −1.732, respectively. Compared to similar results in other developing countries, the estimates appear quite high. When estimated by expenditure (income) groups, the magnitude of the elasticity appears higher among high expenditure groups than among low expenditure groups. Two simulation exercises were undertaken. First, the effect of different excise rates on smoking participation rate, cigarette consumption, tax revenue, and related responses was estimated and highlighted. Second, the same exercise was undertaken to determine the effect of a given increase in the cigarette excise tax on various expenditure groups. The overall results suggest that an increase in the excise tax on cigarettes in Tanzania would reduce cigarette consumption and increase government tax revenue. PMID:27358905

Lymph node status has significant pathologic implications in patients with prostate cancer. In this study, we have performed pathologic analysis of prostatic anterior fat pad (PAFP) excised during robot-assisted radical prostatectomy (RARP) to investigate the potential role of AFP on pathologic staging of prostate cancer. A total of 258 consecutive patients underwent PAFP excision during RARP between July 2007 and June 2009. PAFP was removed and submitted en bloc to the pathology department and evaluated for the presence of lymphoid tissue and metastatic prostate cancer. Retrospective chart review was performed for all patients. Of the 258 patients, 30 (11.6%) had 1 or 2 PAFP lymph nodes and 228 (88.4%) men showed no lymphoid tissue in their PAFPs. Preoperatively, mean PSA level was higher in the former group. There were no significant pathologic differences between the 2 groups. Among the 30 patients with PAFP lymph nodes, 3 were positive for metastatic prostate cancer. All 3 of these patients had high-risk features preoperatively. In 1 patient, the pelvic lymph nodes were negative for metastatic prostate cancer. At 2-year follow-up, PSA level of this patient was undetectable. Herein, we demonstrated that the PAFP contained lymph nodes in over 11% of the patients undergoing RARP at our institution. Prostate cancer was upstaged in 1 patient as a result of PAFP excision. Since this patient is free of biochemical recurrence at 2 years, routine excision and pathologic analysis of PAFP should be considered in prostate cancer patients undergoing radical prostatectomy.

Complete mesocolic excision (CME) has been proposed for colon cancer to improve oncological outcomes. The risks and benefits of laparoscopic CME have not been examined fully. We compared short- and long-term outcomes of CME with a conventional mesocolic excision (non-CME) in laparoscopic right hemicolectomy (RHC) for right-sided colon cancer. In total, 115 patients who underwent laparoscopic RHC with stage I-III right-sided colon cancer at Busan Paik Hospital from August 2007 to October 2011 were enrolled in this case-control study. Three trained colorectal surgeons reviewed videos of the surgeries; patients were divided into two groups: those who underwent a CME (CME group, n = 34) and those who underwent a conventional mesocolic excision (non-CME group, n = 81). There was no significant difference between the CME and non-CME groups in operative time, post-operative complications, or hospital stay. However, the CME group had more lymph nodes harvested (P < 0.001) and lower blood loss (P = 0.016) versus the non-CME group. There was no difference in 5-year disease-free survival rate between the groups, but 5-year overall survival rate was 100% in the CME group and 89.49% in the non-CME group (P < 0.05). Laparoscopic RHC with CME is safe and associated with better 5-year overall survival rate than non-CME for patients with stage I-III right-sided colon cancer. Implementation of CME surgery might improve oncological outcomes for patients with right-sided colon cancer. © 2018 Royal Australasian College of Surgeons.

Polychlorinated biphenyls (PCBs) elicit endocrine disruptive effects in many species, including birds. Tree swallows (Tachycineta bicolor) were studied at eight sites, located in Maryland, Pennsylvania, and New York, with a range of PCB contamination to determine effects on gender and gonadal development of nestling offipring. Blood samples were collected from nestlings and genetic sex was determined by polymerase chain reaction amplification of sex chromatin in nucleated red blood cells. Gonads were excised and fixed for subsequent gross and histologic examination. PCB analyses of twelve-day old nestlings indicated that residue concentrations varied considerably among the eight sites. Of the 145 nestlings examined anatomically, the phenotypic sex ratio was 53% female and 47% male. No intersexes were observed. Histological observations revealed some variation such as numbers of spermatogonia and stages of follicular development among individuals. Genotypic evaluation of the 145 nestlings revealed complete concordance with phenotypic observations. Although there were significant differences in PCB exposure among study sites, there was no evidence of abnormal gonadal development or anatomical gender alteration in nestling Tree swallows.

A G2L2 33-year-old woman presented to our clinic with large verrucous warty masses in labia major, perinea and the end portion of her spine measuring about 15 × 7, 9 × 7 and 8 × 8 cm, which had been enlarged following puberty and pregnancy. Her right upper and left lower limbs had gross congenital lymphedema. The masses were removed by superficial partial vulvectomy with a qualified margin and repaired without skin graft. Pathology report showed lymphangioma circumscriptum. Several months of follow up revealed normal healing and no recurrence. In conclusion, congenital vulvar lymphangioma, which is a rare disorder, can be highly triggered by hormonal-stimulating situations like puberty and pregnancy. Thus, it is better to visit the affected cases in a timely manner in order to excise these lesions before massive enlargement. In our experience, a superficial partial vulvectomy without skin graft can be a sufficient procedure. Obviously, an appropriate approach during and after surgery would be very important for obtaining a desirable healing. © 2018 Japan Society of Obstetrics and Gynecology.

Economic gains and health benefits from a new cigarette tax scheme in Taiwan: a simulation using the CGE model.

Ye, Chun-Yuan; Lee, Jie-Min; Chen, Sheng-Hong

2006-03-10

This study evaluates the impact of an increase in cigarette tax in Taiwan in terms of the effects it has on the overall economy and the health benefits that it brings. The multisector computable general equilibrium (CGE) model was used to simulate the impact of reduced cigarette consumption resulting from a new tax scheme on the entire economy gains and on health benefits. The results predict that because of the new tax scheme, there should be a marked reduction in cigarette consumption but a notable increase in health benefits that include saving between 28,125 and 56,250 lives. This could save NTD 1.222 approximately 2.445 billion (where USD 1 = NTD 34.6) annually in life-threatening, cigarette-related health insurance expenses which exceeds the projected decrease of NTD 1.275 billion in Gross Domestic Product (GDP) because of reduced consumption and therefore tax revenue. Overall, the increased cigarette excise tax will be beneficial in terms of both the health of the general public and the economy as a whole.

To review 7 patients with advanced osteoarticular tuberculous arthritis of the ankle who underwent arthrodesis using a supracondylar femoral nail. All patients showed gross destruction of the articular cartilage of the tibiotalar joint with severe periarticular rarefaction on radiographs. Their pre- and one-year post-operative Foot and Ankle Outcome Scores (FAOS) were compared. All patients underwent joint debridement, complete synovial excision, and arthrodesis using a supracondylar femoral nail, followed by multidrug chemotherapy for 12 months (isoniazid, rifampicin, pyrazinamide, and ethambutol for 3 months, and isoniazid and rifampicin for 9 months). All patients achieved fusion in a mean of 13 weeks and regained their preoperative level of independence. No patient had a relapse, major complications, or hardware failure. At postoperative year one, the mean FAOS for pain improved to 85 from 26, whereas the mean FAOS for quality of life improved to 60 from 5. Tibiotalocalcaneal arthrodesis using a supracondylar femoral nail, combined with debridement and multidrug therapy, enabled a reliable one-stage solution for advanced osteoarticular tuberculosis and early return to function.

In 1940, Scholander suggested that stiffened upper airways remained open and received air from highly compressible alveoli during marine mammal diving. There are few data available on the structural and functional adaptations of the marine mammal respiratory system. The aim of this research was to investigate the anatomical (gross) and structural (compliance) characteristics of excised marine mammal tracheas. Here, we defined different types of tracheal structures, categorizing pinniped tracheas by varying degrees of continuity of cartilage (categories 1-4) and cetacean tracheas by varying compliance values (categories 5A and 5B). Some tracheas fell into more than one category along their length; for example, the harbor seal (Phoca vitulina) demonstrated complete rings cranially, and as the trachea progressed caudally, tracheal rings changed morphology. Dolphins and porpoises had less stiff, more compliant spiraling rings while beaked whales had very stiff, less compliant spiraling rings. The pressure-volume (P-V) relationships of isolated tracheas from different species were measured to assess structural differences between species. These findings lend evidence for pressure-induced collapse and re-inflation of lungs, perhaps influencing variability in dive depth or ventilation rates of the species investigated.

Background This study evaluates the impact of an increase in cigarette tax in Taiwan in terms of the effects it has on the overall economy and the health benefits that it brings. Methods The multisector computable general equilibrium (CGE) model was used to simulate the impact of reduced cigarette consumption resulting from a new tax scheme on the entire economy gains and on health benefits. Results The results predict that because of the new tax scheme, there should be a marked reduction in cigarette consumption but a notable increase in health benefits that include saving between 28,125 and 56,250 lives. This could save NT$1.222~2.445 billion (where US$1 = NT$34.6) annually in life-threatening, cigarette-related health insurance expenses which exceeds the projected decrease of NT$1.275 billion in Gross Domestic Product (GDP) because of reduced consumption and therefore tax revenue. Conclusion Overall, the increased cigarette excise tax will be beneficial in terms of both the health of the general public and the economy as a whole. PMID:16529653

Outcomes of Sinonasal Cancer Treated With Proton Therapy

DOE Office of Scientific and Technical Information (OSTI.GOV)

Dagan, Roi, E-mail: rdagan@floridaproton.org; Department of Radiation Oncology, University of Florida, Jacksonville, Florida; Bryant, Curtis

Purpose: To report disease outcomes after proton therapy (PT) for sinonasal cancer. Methods and Materials: Eighty-four adult patients without metastases received primary (13%) or adjuvant (87%) PT for sinonasal cancers (excluding melanoma, sarcoma, and lymphoma). Common histologies were olfactory neuroblastoma (23%), squamous cell carcinoma (22%), and adenoid cystic carcinoma (17%). Advanced stage (T3 in 25% and T4 in 69%) and high-grade histology (51%) were common. Surgical procedures included endoscopic resection alone (45%), endoscopic resection with craniotomy (12%), or open resection (30%). Gross residual disease was present in 26% of patients. Most patients received hyperfractionated PT (1.2 Gy [relative biological effectiveness (RBE)] twicemore » daily, 99%) and chemotherapy (75%). The median PT dose was 73.8 Gy (RBE), with 85% of patients receiving more than 70 Gy (RBE). Prognostic factors were analyzed using Kaplan-Meier analysis and proportional hazards regression for multiple regression. Dosimetric parameters were evaluated using logistic regression. Serious, late grade 3 or higher toxicity was reported using the National Cancer Institute Common Terminology Criteria for Adverse Events, version 4. The median follow-up was 2.4 years for all patients and 2.7 years among living patients. Results: The local control (LC), neck control, freedom from distant metastasis, disease-free survival, cause-specific survival, and overall survival rates were 83%, 94%, 73%, 63%, 70%, and 68%, respectively, at 3 years. Gross total resection and PT resulted in a 90% 3-year LC rate. The 3-year LC rate was 61% for primary radiation therapy and 59% for patients with gross disease. Gross disease was the only significant factor for LC on multivariate analysis, whereas grade and continuous LC were prognostic for overall survival. Six of 12 local recurrences were marginal. Dural dissemination represented 26% of distant recurrences. Late toxicity occurred in 24% of patients (with grade 3 or higher unilateral vision loss in 2%). Conclusions: Dose-intensified, hyperfractionated PT with or without concurrent chemotherapy results in excellent LC after gross total resection, and results in patients with gross disease are encouraging. Patients with high-grade histology are at greater risk of death from distant dissemination. Continuous LC is a major determinant of survival justifying aggressive local therapy in nearly all cases.« less

To elucidate the clinical behavior, treatment, and outcomes of tenosynovial giant cell tumors (TGCT) involving the temporomandibular joint (TMJ) and adjacent temporal bone. Retrospective case series with histopathologic review. A retrospective chart review was performed identifying and collecting data from all cases of TGCT involving the TMJ and adjacent temporal bone that were treated at the authors' center between January 1960 and December 2015. Eleven histopathologically confirmed cases met inclusion criteria. The median age at diagnosis was 49 years, eight patients were men, and the median follow-up was 116 months. Computed tomographic (CT) imaging revealed a lytic expansile mass centered on the TMJ. Magnetic resonance imaging (MRI) most commonly exhibited hypointense signal on precontrast T1- and T2-weighted sequences and variable postcontrast enhancement. The median delay in diagnosis was 24 months, and the most common presenting symptoms were hearing loss and pain. All patients underwent surgical resection, eight receiving gross total removal, one receiving near total removal, and two patients from early in the series receiving subtotal resection with neoadjuvant or adjuvant radiation. Histopathological review of surgical specimens revealed chondroid metaplasia in seven tumors. Eight of nine cases receiving gross total or near total resection have no evidence of recurrence to date. TGCT of the TMJ and temporal bone are rare and locally aggressive tumors that commonly present with nonspecific symptoms. A careful review of CT and MRI followed by early biopsy is critical in establishing an accurate diagnosis and facilitating appropriate treatment. TGCT of the TMJ more commonly contain chondroid metaplasia when compared to TGCT at other anatomic locations. Gross total resection is achievable in most cases and offers long-term cure. Radiation may be considered for recurrent disease or adjuvant therapy following subtotal resection. 4.

2010-11-01

Spinal muscular atrophy (SMA) is a neuromuscular disorder characterized by degeneration of alpha motor neurons. This case report describes an aquatic therapy program and the outcomes for a 3-year-old girl with type III SMA. Motor skills were examined using the 88-item Gross Motor Function Measure (GMFM), the Peabody Developmental Motor Scales (PDMS-2), and the GAITRite system. The child received aquatic therapy twice per week for 45-min sessions, for 14 weeks. The intervention included aquatic activities designed to improve gross motor skills and age-appropriate functional mobility. The GMFM total score improved by 11% following the intervention. The Standing Dimension score improved by 28% and the Walking, Running, and Jumping Dimension score improved by 18%. The gross motor quotient for the PDMS-2 improved from 66 to 74. The child's gait showed improvement in walking velocity, stride length, and single-limb support time as a percentage of the gait cycle. The outcomes of this case report demonstrate the successful improvement of gross motor function and gait in a 3-year-old child with SMA. This study provides clinical information for therapists utilizing aquatic therapy as a modality for children with neuromuscular disorders.

Hagfish consume carrion, potentially exposing them to hypoxia, hypercapnia, and high environmental ammonia (HEA). We investigated branchial and cutaneous ammonia handling strategies by which Pacific hagfish ( Eptatretus stoutii ) tolerate and recover from high ammonia loading. Hagfish were exposed to HEA (20 mmol/l) for 48 h to elevate plasma total ammonia (T Amm ) levels before placement into divided chambers for a 4-h recovery period in ammonia-free seawater where ammonia excretion ( J Amm ) was measured independently in the anterior and posterior compartments. Localized HEA exposures were also conducted by subjecting hagfish to HEA in either the anterior or posterior compartments. During recovery, HEA-exposed animals increased J Amm in both compartments, with the posterior compartment comprising ~20% of the total J Amm compared with ~11% in non-HEA-exposed fish. Plasma T Amm increased substantially when whole hagfish and the posterior regions were exposed to HEA. Alternatively, plasma T Amm did not elevate after anterior localized HEA exposure. J Amm was concentration dependent (0.05-5 mmol/l) across excised skin patches at up to eightfold greater rates than in skin sections that were excised from HEA-exposed hagfish. Skin excised from more posterior regions displayed greater J Amm than those from more anterior regions. Immunohistochemistry with hagfish-specific anti-rhesus glycoprotein type c (α-hRhcg; ammonia transporter) antibody was characterized by staining on the basal aspect of hagfish epidermis while Western blotting demonstrated greater expression of Rhcg in more posterior skin sections. We conclude that cutaneous Rhcg proteins are involved in cutaneous ammonia excretion by Pacific hagfish and that this mechanism could be particularly important during feeding.

Consumption of cigarettes and combustible tobacco--United States, 2000-2011.

PubMed

2012-08-03

Smoking cigarettes and other combustible tobacco products causes adverse health outcomes, particularly cancer and cardiovascular and pulmonary diseases. A priority of the U.S. Department of Health and Human Services is to develop innovative, rapid-response surveillance systems for assessing changes in tobacco use and related health outcomes. The two standard approaches for measuring smoking rates and behaviors are 1) surveying a representative sample of the public and asking questions about personal smoking behaviors and 2) estimating consumption based on tobacco excise tax data. Whereas CDC regularly publishes findings on national and state-specific smoking rates from public surveys, CDC has not reported consumption estimates. The U.S. Department of Agriculture (USDA), which previously provided such estimates, stopped reporting on consumption in 2007. To estimate consumption for the period 2000-2011, CDC examined excise tax data from the U.S. Department of Treasury's Alcohol and Tobacco Tax and Trade Bureau (TTB); consumption estimates were calculated for cigarettes, roll-your-own tobacco, pipe tobacco, and small and large cigars. From 2000 to 2011, total consumption of all combustible tobacco decreased from 450.7 billion cigarette equivalents to 326.6, a 27.5% decrease; per capita consumption of all combustible tobacco products declined from 2,148 to 1,374, a 36.0% decrease. However, while consumption of cigarettes decreased 32.8% from 2000 to 2011, consumption of loose tobacco and cigars increased 123.1% over the same period. As a result, the percentage of total combustible tobacco consumption composed of loose tobacco and cigars increased from 3.4% in 2000 to 10.4% in 2011. The data suggest that certain smokers have switched from cigarettes to other combustible tobacco products, most notably since a 2009 increase in the federal tobacco excise tax that created tax disparities between product types.

Initial experience of restorative proctocolectomy for ulcerative colitis by transanal total mesorectal rectal excision and single-incision abdominal laparoscopic surgery.

Laparoscopic surgery is well established for colon cancer, with defined benefits. Use of laparoscopy for the performance of restorative proctocolectomy (RPC) with ileoanal anastomosis is more controversial. Technical aspects include difficult dissection of the distal rectum and a potentially increased risk of anastomotic leakage through multiple firings of the stapler. In an attempt to overcome these difficulties we have used the technique of transanal rectal excision to perform the proctectomy. This paper describes the technique, which is combined with an abdominal approach using a single-incision platform (SIP). Data were collected prospectively for consecutive operations between May 2013 and October 2015, including all cases of restorative proctocolectomy with ileoanal pouch anastomosis performed laparoscopically. Only patients having a transanal total mesorectal excision (TaTME) assisted by SIP were included. The indication for RPC was ulcerative colitis (UC) refractory to medical treatment. The procedure was performed on 16 patients with a median age of 46 (26-70) years. The male:female ratio was 5:3 and the median hospital stay was 6 (3-20) days. The median operation time was 247 (185-470) min and the overall conversion rate to open surgery was 18.7%. The 30-day surgical complication rate was 37.5% (Clavien-Dindo 1 in four patients, 2 in one patient and 3 in one patient). One patient developed anastomotic leakage 2 weeks postoperatively. This initial study has demonstrated the feasibility and safety of TaTME combined with SIP when performing RPC with ileal pouch-anal anastomosis for UC.

Intralesional cryotherapy versus excision and corticosteroids or brachytherapy for keloid treatment: study protocol for a randomised controlled trial

PubMed Central

2013-01-01

Background Keloids are a burden for patients due to physical, aesthetic and social complaints and treatment remains a challenge because of therapy resistance and high recurrence rates. The main goal of treatment is to improve the quality of life (QoL); this implies that, apart from surgical outcomes, patient-reported outcome measures (PROMs) need to be taken into account. Decision making in keloid treatment is difficult due to heterogeneity of the condition and the lack of comparative studies. Methods/Design This is a multicentre, randomised controlled open trial that compares 1) intralesional cryotherapy versus excision and corticosteroids for primary keloids, and 2) intralesional cryotherapy versus excision and brachytherapy for therapy-resistant keloids. The primary outcome is the Patient and Observer Scar Assessment Scale (POSAS), a 12-item scale (with score 12 indicating the best and 120 indicating the worst scar imaginable). A difference of six points on the total score is considered to be of clinical importance. Secondary outcomes are recurrence rates, volume reduction, Skindex-29 scores, SF-36 scores and complication rates. Primary and secondary outcome measurements are taken at baseline, and at 2, 12, 26 and 52 weeks postoperatively. For analysis, a linear mixed model is used. A total of 176 patients will be included over a period of 2.5 years. The protocol is approved by the Medical Ethics Committee of the Erasmus University Medical Centre Rotterdam and follows good clinical practice guidelines. Discussion The outcomes of this study will improve evidence-based decision making for the treatment of keloids, as well as patient education. Trial registration Dutch Trial Register NTR4151.

To date, there is no standard treatment for recurrent glioblastoma. We analyzed the feasibility of second surgery plus carmustine wafers followed by intravenous fotemustine. Retrospectively, we analyzed patients with recurrent glioblastoma treated with this multimodal strategy. Twenty-four patients were analyzed. The median age was 53.6; all patients had KPS between 90 and 100; 19 patients (79%) performed a gross total resection > 98% and 5 (21%) a gross total resection > 90%. The median progression-free survival from second surgery was 6 months (95% CI 3.9-8.05) and the median OS was 14 months (95% CI 11.1-16.8 months). Toxicity was predominantly haematological: 5 patients (21%) experienced grade 3-4 thrombocytopenia and 3 patients (12%) grade 3-4 leukopenia. This multimodal strategy may be feasible in patients with recurrent glioblastoma, in particular, for patients in good clinical conditions.

1984-01-01

In situ measurement of sudden leaf water potential changes has not been performed under field conditions. A laboratory investigation involving the measurement of leaf water potential prior to and 2 to 200 minutes after excision of citrus leaves (Citrus jambhiri) showed good linear correlation (r = 0.99) between in situ leaf psychrometer and Scholander pressure chamber measurements. Following this, a field investigation was conducted which involved psychrometric measurement prior to petiole excision and 1 minute after excision. Simultaneous pressure chamber measurements were performed on neighboring leaves prior to the time of excision and then on the psychrometer leaf about 2 minutes after excision. These data indicate that within the first 2 minutes after excision, psychrometer and pressure chamber measurements were linearly correlated (r = 0.97). Under high evaporative demand conditions, the rate of water potential decrease was between 250 and 700 kilopascals in the first minute after excision. These results show that the thermocouple psychrometer can be used as a dynamic and nondestructive field technique for monitoring leaf water potential.

Frequency and characteristics of melanomas missed at a pigmented lesion clinic: a registry-based study.

2004-10-01

To ensure the removal of all melanomas at an early phase, a number of benign lesions are currently excised for diagnostic evaluation. Nevertheless, little is known about the frequency of melanomas missed (neither recognized nor excised for diagnostic verification) by early detection practices. This study aimed to investigate the diagnostic performance of a specialized pigmented lesion clinic (PLC) through linkage with a local cancer registry. In 1997, 1741 individuals resident in the area of Florence and Prato, Italy, the catchment area of the Tuscany Cancer Registry (RTT), were consecutively examined at a specialized PLC that has been running since 1992 at the Department of Dermatology of Florence. The outcomes of dermatological consultations retrieved from PLC case notes were compared with all the diagnoses of both in situ and invasive melanoma recorded by the RTT until 31 December 1999. The performance of the PLC in detecting cutaneous melanoma was evaluated in terms of sensitivity, specificity and predictive values, with the RTT data as the gold standard. In the population examined at the PLC, 15 newly incident melanomas, all histologically demonstrated, were recorded by the RTT. In 13 of the 15 cases, excision of the lesion had been recommended by PLC staff, while two melanomas, one in situ and one level II 0.60 mm thick invasive, were missed and were subsequently excised 586 and 824 days, respectively, after the first PLC examination. The clinical and dermoscopic features of the invasive lesion were in agreement with a 'featureless' melanoma, and lacked the well-established parameters of malignancy. A total of 67 benign pigmented skin lesions were excised for diagnostic evaluation. Thus the PLC showed a sensitivity in detecting cutaneous melanoma of 86.7% (95% confidence interval [CI] 85.1-88.3%), a specificity of 95.4% (95% CI 94.3-96.3%), a positive predictive value of 13.7% (95% CI 12.1-15.3%) and a negative predictive value of 99.9% (95% CI 99.7-100.0%). The ratio of melanomas to benign skin lesions excised was 1:5.1. In conclusion, specialized examination of pigmented skin lesions at the PLC offered good level of diagnostic performance, with an acceptable cost in terms of benign lesions removed and overall a low risk of missing melanomas.

Resistance to Nucleotide Excision Repair of Bulky Guanine Adducts Opposite Abasic Sites in DNA Duplexes and Relationships between Structure and Function

2015-01-01

The nucleotide excision repair of certain bulky DNA lesions is abrogated in some specific non-canonical DNA base sequence contexts, while the removal of the same lesions by the nucleotide excision repair mechanism is efficient in duplexes in which all base pairs are complementary. Here we show that the nucleotide excision repair activity in human cell extracts is moderate-to-high in the case of two stereoisomeric DNA lesions derived from the pro-carcinogen benzo[a]pyrene (cis- and trans-B[a]P-N 2-dG adducts) in a normal DNA duplex. By contrast, the nucleotide excision repair activity is completely abrogated when the canonical cytosine base opposite the B[a]P-dG adducts is replaced by an abasic site in duplex DNA. However, base excision repair of the abasic site persists. In order to understand the structural origins of these striking phenomena, we used NMR and molecular spectroscopy techniques to evaluate the conformational features of 11mer DNA duplexes containing these B[a]P-dG lesions opposite abasic sites. Our results show that in these duplexes containing the clustered lesions, both B[a]P-dG adducts adopt base-displaced intercalated conformations, with the B[a]P aromatic rings intercalated into the DNA helix. To explain the persistence of base excision repair in the face of the opposed bulky B[a]P ring system, molecular modeling results suggest how the APE1 base excision repair endonuclease, that excises abasic lesions, can bind productively even with the trans-B[a]P-dG positioned opposite the abasic site. We hypothesize that the nucleotide excision repair resistance is fostered by local B[a]P residue—DNA base stacking interactions at the abasic sites, that are facilitated by the absence of the cytosine partner base in the complementary strand. More broadly, this study sets the stage for elucidating the interplay between base excision and nucleotide excision repair in processing different types of clustered DNA lesions that are substrates of nucleotide excision repair or base excision repair mechanisms.

Physical therapy students’ perceptions of team-based learning in gross anatomy using the Team-Based Learning Student Assessment Instrument

PubMed Central

2014-01-01

Purpose: The objective of this study was to assess physical therapy student perceptions of team-based learning (TBL) in a graduate level gross anatomy course using the TBL Student Assessment Instrument (TBL-SAI). Methods: The TBL-SAI was administered to 85 doctor of physical therapy (DPT) students, comprising three cohorts (classes of 2013, 2014, and 2015), who successfully completed a gross anatomy course where TBL was implemented. The TBL-SAI surveys 33 items, each rated from one (strongly disagree) to five (strongly agree) and measures three subscales: students’ perceptions of accountability, preference for lecture or TBL, and student satisfaction. Results: The means for each subscale and the total TBL-SAI score for each cohort fell above the neutral score. The 2015 group (mean, 37.97; 95% confidence interval [CI], 35.67 to 40.26) reported significantly higher satisfaction than that of the 2013 group (mean, 32.71; 95% CI, 30.31 to 35.05) and the 2014 group (mean, 33.11; 95% CI, 30.69 to 35.53). The 2015 group (mean, 125.3; 95% CI, 120.6 to 130.3) also had a significantly higher total score than that of the 2013 group (mean, 115.6; 95% CI, 110.5 to 120.5). Conclusion: The physical therapy students reported an overall positive experience in using TBL to learn gross anatomy in terms of accountability, preference for learning mode, and satisfaction. This positive experience with TBL was accompanied by their successful academic performance. Given the traits and learning preferences in this generation of graduate students, TBL could be a teaching method that is received positively elsewhere and results in successful academic performance and learning.

The object of this study was to detect any possible relation between the current gross motor function score for cerebral palsy children and their physical growth parameters. We measured 71 children with spastic cerebral palsy (35 diplegic, 25 quadriplegic and 11 hemiplegic) and a control group of 80 normal children. Measures taken for cerebral palsy and normal children included stature, weight, head circumference and mid upper-arm circumference, and, additionally for the cerebral palsied children, duration of the disease, birth weight, presence or absence of orofacial dysfunction, distribution of paralysis and degree of spasticity. Motor abilities were measured using the Gross Motor Function Measure. Results showed a significant decrease in the stature, current weight, head circumference and mid upper-arm circumference of both sexes of the quadriplegic children, and significant decreases in the current weight of the diplegic girls and the head circumference of the hemiplegic girls. There were also significant decreases in all scores of the quadriplegic children compared to the diplegic and hemiplegic children. Diplegic children had significantly decreased standing, walking and running, and total scores, compared to the hemiplegic children. Total score at age of testing was independently predicted by the duration of the disease, distribution of paralysis, presence or absence of orofacial dysfunction, spasticity index and the current body weight. Our findings indicate that in spastic cerebral palsy the physical growth parameters were markedly decreased in the quadriplegic form compared to other forms. Only current body weight, from the growth parameters, in addition to other relevant clinical data, can be considered predictors of the current gross motor abilities of those children.

Asynchronous online discussion forums are common in blended learning models and are popular with students. A previous report has suggested that participation in these forums may assist student learning in a gross anatomy subject but it was unclear as to whether more academically able students post more often or whether participation led to improved learning outcomes. This study used a path model to analyze the contribution of forum participation, previous academic ability, and student campus of enrolment to final marks in a multicampus gross anatomy course for physiotherapy students. The course has a substantial online learning management system (LMS) that incorporates asynchronous forums as a learning tool, particularly to answer learning objectives. Students were encouraged to post new threads and answer queries in threads started by others. The forums were moderated weekly by staff. Discussion forums were the most used feature of the LMS site with 31,920 hits. Forty-eight percent of the students posted at least once with 186 threads initiated by students and a total of 608 posts. The total number of posts made a significant direct contribution to final mark (P = 0.008) as did previous academic ability (P = 0.002). Although campus did not contribute to final mark, there was a trend for students at the campus where the course coordinator was situated to post more often than those at the other campus (P = 0.073). These results indicate that asynchronous online discussion forums can be an effective tool for improving student learning outcomes as evidenced by final marks in gross anatomy teaching.

Pathogenicity islands (PAIs) are regions of the chromosome of pathogenic bacteria that harbor virulence genes, which were probably acquired by lateral gene transfer. Several PAIs can excise from the bacterial chromosome by site-specific recombination and in this review have been denominated "excisable PAIs". Here, the characteristic of some of the excisable PAIs from Salmonella enterica and the possible role and impact of the excision process on bacterial virulence is discussed. Understanding the role of PAI excision could provide important insights relative to the emergence, evolution and virulence of pathogenic enterobacteria. Copyright © 2016 Institut Pasteur.

Arthroscopic excision of ganglion cysts.

PubMed

Bontempo, Nicholas A; Weiss, Arnold-Peter C

2014-02-01

Arthroscopy is an advancing field in orthopedics, the applications of which have been expanding over time. Traditionally, excision of ganglion cysts has been done in an open fashion. However, more recently, studies show outcomes following arthroscopic excision to be as good as open excision. Cosmetically, the incisions are smaller and heal faster following arthroscopy. In addition, there is the suggested benefit that patients will regain function and return to work faster following arthroscopic excision. More prospective studies comparing open and arthroscopic excision of ganglion cysts need to be done in order to delineate if there is a true functional benefit. Copyright © 2014 Elsevier Inc.

2018-06-24

No consensus exists regarding the best surgical strategy to achieve clear surgical margins while minimizing tissue excision when definitely excising lentigo maligna melanoma in situ (LM). The staged margin controlled excision (SMEX) technique is a modification of the spaghetti technique that allows surgeons to minimize margins and ensure complete excision of LM. Our objectives were twofold: a) to evaluate the effectiveness of SMEX for treatment of LM and b) detail the SMEX technique. A retrospective chart review of adult patients who underwent the SMEX technique for treatment of LM from 2011 to 2016 was conducted. Twenty-four patients were identified with predominantly facial lesions. The mean defect size was 12.1 cm 2 . A mean number of two SMEX procedures, with an average margin of 9 mm, were required to obtain complete excision of the LM. Using SMEX, we achieved 100% clearance of LM over a median follow up period of 18 months, with a range of 1-63 months. SMEX offers a reliable surgical excision method that ensures complete excision of LM in a cosmetically sensitive manner. The recurrence outcomes of SMEX are comparable, if not better, than those of alternative excision techniques in the literature. © 2018 Wiley Periodicals, Inc.

Understanding the relationship between sales of legal cigarettes and deaths: A case-study in Brazil.

Szklo, André Salem; Iglesias, Roberto Magno; de Souza, Mirian Carvalho; Szklo, Moysés; Cavalcante, Tânia Maria; de Almeida, Liz Maria

2017-01-01

Brazil has experienced a large decline in cigarette consumption in the last 25years. However, the most recent annual reports from the tobacco industry market leader in Brazil did not show a decrease in its gross profits. This is particularly important because tobacco industry donations/sponsorships come directly from the industry's reported gross-profits and are used to subvert health policies. The aim of the present study was to estimate (i) tobacco industry's gross-profit from legal cigarettes sales, and (ii) all-cause smoking-attributable deaths (SADs) among current Brazilian smokers who consumed legal cigarettes in 2013. We collected information on prevalence of legal cigarette use, cigarette consumption, price per cigarette pack among individuals aged ≥35years from the Global Adult Tobacco Survey, legal cigarettes sales (e.g., average costs and total volume of sales) provided by the Federal Secretariat of Revenues, and population mortality from the available vital statistics. With a gross-profit of US$1.378 billion (1.307-1.434) from sales of 54.6 billion sticks of cigarettes (53.4-55.5) to 8,424,510 smokers aged 35years and older in Brazil in 2013, cumulative SADs were estimated at 96,012 (85,647-107,654) (around 34% of cumulative SADs also including current smoking of illegal cigarettes and past smoking), i.e., one SAD was equivalent to a gross-profit of US$14,352 (12,140-16,743). Our results revealed the association between sales of cigarettes, gross-profits, and deaths in Brazil. As tobacco industry donations/sponsorships originate from industry's gross profits, which, in turn, depend on cigarette sales, our findings may be useful for increasing "moral pressure" on individuals and institutions and help countries in stopping tobacco industry interference in health policies.

Alar base reduction: the boomerang-shaped excision.

PubMed

Foda, Hossam M T

2011-04-01

A boomerang-shaped alar base excision is described to narrow the nasal base and correct the excessive alar flare. The boomerang excision combined the external alar wedge resection with an internal vestibular floor excision. The internal excision was inclined 30 to 45 degrees laterally to form the inner limb of the boomerang. The study included 46 patients presenting with wide nasal base and excessive alar flaring. All cases were followed for a mean period of 18 months (range, 8 to 36 months). The laterally oriented vestibular floor excision allowed for maximum preservation of the natural curvature of the alar rim where it meets the nostril floor and upon its closure resulted in a considerable medialization of alar lobule, which significantly reduced the amount of alar flare and the amount of external alar excision needed. This external alar excision measured, on average, 3.8 mm (range, 2 to 8 mm), which is significantly less than that needed when a standard vertical internal excision was used ( P < 0.0001). Such conservative external excisions eliminated the risk of obliterating the natural alar-facial crease, which did not occur in any of our cases. No cases of postoperative bleeding, infection, or vestibular stenosis were encountered. Keloid or hypertrophic scar formation was not encountered; however, dermabrasion of the scars was needed in three (6.5%) cases to eliminate apparent suture track marks. The boomerang alar base excision proved to be a safe and effective technique for narrowing the nasal base and elimination of the excessive flaring and resulted in a natural, well-proportioned nasal base with no obvious scarring. © Thieme Medical Publishers.

Reproductive effort in invasive and non-invasive Rubus.

PubMed

McDowell, Susan C; Turner, David P

2002-10-01

We quantified the physiological costs and the total amount of resources allocated to reproduction in two closely related species of Rubus, one of which is invasive. These two species share several morphological and life-history characteristics and grow together in the Pacific Northwestern United States. Reproductive effort was manipulated in canes of both species by removing flower buds. The non-invasive species, R. ursinus, exhibited significantly greater water stress in the reproductive canes, as indicated by lower leaf water potential (Ψ) and reduced stomatal conductance (g s ). This species also showed a reduction in leaf nitrogen concentration ([N]) associated with reproduction. Combined, these factors led to reduced photosynthesis (A) on a diurnal basis, lower water-use efficiency as inferred from δ 13 C, and reduced photosynthetic capacity. All of these effects were more pronounced during the fruiting stage than in the flowering stage. The invasive species, R. discolor, showed no changes in water stress, [N], δ 13 C, or A associated with reproduction. A model was used to estimate total gross photosynthesis (A gross ) for reproductive and non-reproductive canes of both species over cane lifetime. Reproduction was associated with a greater decline in A gross for the non-invasive R. ursinus than for the invasive R. discolor. Although R. discolor allocated more resources directly to flowers and fruit than R. ursinus, the invasive species had significantly lower reproductive effort, or total amount of resources diverted from vegetative activity to reproduction, than the non-invasive species. By minimizing the reduction of photosynthesis associated with reproduction, this invasive species may be able to minimize the trade-offs commonly associated with reproduction.

Quality of water and chemistry of bottom sediment in the Rillito Creek basin, Tucson, Arizona, 1986-92

Tadayon, Saeid; Smith, C.F.

1994-01-01

Data were collected on physical properties and chemistry of 4 surface water, l4 ground water, and 4 bottom sediment sites in the Rillito Creek basin where artificial recharge of surface runoff is being considered. Concentrations of suspended sediment in streams generally increased with increases in streamflow and were higher during the summer. The surface water is a calcium and bicarbonate type, and the ground water is calcium sodium and bicarbonate type. Total trace ek=nents in surface water that exceeded the U.S. Environmental Protection Agency primary maximum contaminant levels for drinking-water standards were barium, beryllium, cadmium, chromium, lead, mercury and nickel. Most unfiltered samples for suspended gross alpha as uranium, and unadjusted gross alpha plus gross beta in surface water exceeded the U.S. Environmental Protection Agency and the State of Arizona drinking-water standards. Comparisons of trace- element concentrations in bottom sediment with those in soils of the western conterminous United States generally indicate similar concentrations for most of the trace elements, with the exceptions of scandium and tin. The maximum concentration of total nitrite plus nitrate as nitrogen in three ground- samples and total lead in one ground-water sample exceeded U.S. Environmental Protection Agency primary maximum contaminant levels for drinking- water standards, respectively. Seven organochlorine pesticides were detected in surface-water samples and nine in bottom-sediment samples. Three priority pollutants were detected in surface water, two were detected in ground water, and eleven were detected in bottom sediment. Low concentrations of oil and grease were detected in surface-water and bottom- sediment samples.

The Influence of Neurodevelopmental Treatment on Transforming Growth Factor-β1 Levels and Neurological Remodeling in Children With Cerebral Palsy.

PubMed

Tao, Weiyuan; Lu, Zuneng; Wen, Fang

2016-11-01

Neurodevelopmental treatment is an advanced therapeutic approach for the neural rehabilitation of children with cerebral palsy. Cerebral palsy represents a spectrum of neurological disorders primarily affecting gross motor function. The authors investigated the effects of neurodevelopmental treatment on serum levels of transforming growth factor-β1 (TGF-β1), a neuroprotective cytokine, and improvements to motor skills. Serum TGF-β1 levels and total score of the Gross Motor Function Measure-88 (GMFM-88) were significantly higher in children with cerebral palsy who underwent neurodevelopmental treatment compared to untreated patients (P < .01). Furthermore, the improved GMFM-88 total scores after neurodevelopmental treatment were significantly higher in children under the age of 3 with cerebral palsy than in older patients (P < .01). The authors demonstrate that the integration of TGF-β1 levels and GMFM-88 total score could be used to assess the efficacy of neurodevelopmental treatment. Moreover, the findings provide further scientific support for the early intervention and neurological rehabilitation of young children with cerebral palsy. © The Author(s) 2016.

Surgical excision and immediate postoperative radiotherapy versus cryotherapy and intralesional steroids in the management of keloids: a prospective clinical trial.

To compare the efficacy and tolerability of surgical excision and radiotherapy with those of cryotherapy and intralesional steroid treatment of keloids. Twenty-six patients with a total of 76 keloids were enrolled in this study. Nineteen patients with 44 keloids underwent surgical excision combined with immediate 12-Gy irradiation (group A) while the remaining 9 patients with 32 keloids received multiple sessions of intralesional steroid treatment after cryotherapy which continued until flattening of lesion(s) occurred (group B). Two patients were included in both treatment groups. All patients were followed up at regular intervals for at least 1 year. In both treatment groups, keloids responded well without any major side effect. While patients of group A were all satisfied, those of group B (with a mean number of treatment sessions of 5.84 +/- 2.51) experienced more side effects, a more prolonged course, a higher recurrence rate and less satisfaction. This study showed that surgery plus immediate postoperative irradiation was an effective and relatively safe choice for treatment of keloids. Although cryotherapy combined with intralesional steroids was associated with more side effects and higher relapse rates, it could be a good choice for small and newly formed keloids.

Describe single-stage removal of head and neck venous malformations using percutaneous embolization with n-butyl cyanoacrylate (n-BCA) glue prior to surgical resection. Case series with chart review. Tertiary-care pediatric hospital. A total of 169 venous malformations were identified between 2000 and 2012, and 102 (60.1%) were in the head and neck. Thirty-five of 102 (34.3%) were observed, 56 of 102 (54.9%) had invasive therapy, and 11 of 102 (10.8%) underwent n-BCA embolization and surgery ("GES procedure"). The median age of the glue embolization and surgery cohort was 14 years (range, 6-19), and 7 of 11 (63.6%) were female. Treated venous malformations involved the oral cavity/tongue (4/11; 36.4%) and parotid/face (7/11; 63.6%). During facial lesion excision, intraoperative facial nerve monitoring was used. All surgical sites (11/11) were closed primarily. No patient in this cohort had any posttreatment nerve deficits, dysarthria, and dysphagia or lesion persistence. Localized venous malformations can be treated with preoperative percutaneous embolization with n-BCA glue followed by surgical excision. This technique, with selective motor nerve monitoring, appears safe and allows for complete venous malformation removal with limited nerve dissection, to allow maximal tissue and functional preservation.

This paper investigates terahertz (THz) imaging and classification of freshly excised murine xenograft breast cancer tumors. These tumors are grown via injection of E0771 breast adenocarcinoma cells into the flank of mice maintained on high-fat diet. Within 1 h of excision, the tumor and adjacent tissues are imaged using a pulsed THz system in the reflection mode. The THz images are classified using a statistical Bayesian mixture model with unsupervised and supervised approaches. Correlation with digitized pathology images is conducted using classification images assigned by a modal class decision rule. The corresponding receiver operating characteristic curves are obtained based on the classification results. A total of 13 tumor samples obtained from 9 tumors are investigated. The results show good correlation of THz images with pathology results in all samples of cancer and fat tissues. For tumor samples of cancer, fat, and muscle tissues, THz images show reasonable correlation with pathology where the primary challenge lies in the overlapping dielectric properties of cancer and muscle tissues. The use of a supervised regression approach shows improvement in the classification images although not consistently in all tissue regions. Advancing THz imaging of breast tumors from mice and the development of accurate statistical models will ultimately progress the technique for the assessment of human breast tumor margins.

Halo congenital melanocytic nevus (CMN) associated with vitiligo is rare, especially with regard to CMN excision. Only two reports of excision of halo CMN following repigmentation of vitiligo are found in the literature. We present a case of a girl with halo CMN and periorbital vitiligo. The halo CMN was excised and followed by spontaneous improvement of vitiligo. The result suggests excision of the inciting lesion may be a promising way to control vitiligo. © 2015 Wiley Periodicals, Inc.

Because definitive long-term results are not yet available, the oncological safety of laparoscopic surgery for treatment of rectal cancer remains unproven. The aim of this prospective non-randomised study was to assess the feasibility and short-term outcome of laparoscopic total mesorectal excision (LTME) after 25--30 Gy preoperative radiotherapy and to compare the results with a matched-control group of open TME (OTME). A series of 41 patients with primary rectal cancer underwent LTME for rectal cancer and were matched with a historical control group of 41 patients who underwent OTME. Both groups received preoperative short-term radiotherapy. There was no mortality in the LTME group and 2% mortality in the OTME group. The overall postoperative morbidity was 37% in the LTME group and 51% in the OTME group, including an anastomotic leakage of 9 and 14% in the LTME and OTME groups respectively. A positive circumferential margin was found in 7% of patients in the LTME group and in 12% of the patients in the OTME group. This study shows that LTME is technically feasible and can be performed safely. We show at least a similar surgical completeness using a laparoscopic technique compared with open surgery.

Stop female genital mutilation: appeal to the international dermatologic community.

PubMed

Morrone, Aldo; Hercogova, Jana; Lotti, Torello

2002-05-01

Female genital mutilation (FGM) is a traditional cultural practice, but also a form of violence against girls, which affects their lives as adult women. FGM comprises a wide range of procedures: the excision of the prepuce; the partial or total excision of the clitoris (clitoridectomy) and labia; or the stitching and narrowing of the vaginal orifice (infibulation). The number of girls and women who have been subjected to FGM is estimated at around 137 million worldwide and 2 million girls per year are considered at risk. Most females who have undergone mutilation live in 28 African countries. Globalization and international migration have brought an increased presence of circumcised women in Europe and developed countries. Healthcare specialists need to be made aware and trained in the physical, psychosexual, and cultural aspects and effects of FGM and in the response to the needs of genitally mutilated women. Health education programs targeted at immigrant communities should include information on sexuality, FGM, and reproduction. Moreover, healthcare workers should both discourage women from performing FGM on their daughters and receive information on codes of conduct and existing laws. The aim is the total eradication of all forms of FGM.

State-Specific Liquor Excise Taxes and Retail Prices in Eight U.S. States, 2012

We investigated the relationship between state excise taxes and liquor prices in eight states, using 2012 data for 45 brands. We made 6,042 price observations among 177 liquor stores with online prices. Using a hierarchical model, we examined the relationship between excise taxes and product prices. State excise taxes were significantly related to liquor prices, with an estimated pass-through rate of 0.93. The proportion of price accounted for by excise taxes averaged 7.0%. We find that excise taxes do increase the price of alcohol, but states are not taking advantage of this opportunity to reduce alcohol-related morbidity and mortality. PMID:24159914

Work, T M; Aeby, G S; Hughen, K A

2016-01-01

The authors documented gross and microscopic morphology of lesions in corals on 7 islands spanning western, southern, and eastern Micronesia, sampling 76 colonies comprising 30 species of corals among 18 genera, with Acropora, Porites, and Montipora dominating. Tissue loss comprised the majority of gross lesions sampled (41%), followed by discoloration (30%) and growth anomaly (29%). Of 31 cases of tissue loss, most lesions were subacute (48%), followed by acute and chronic (26% each). Of 23 samples with discoloration, most were dark discoloration (40%), with bleaching and other discoloration each constituting 30%. Of 22 growth anomalies, umbonate growth anomalies composed half, with exophytic, nodular, and rugose growth anomalies composing the remainder. On histopathology, for 9 cases of dark discoloration, fungal infections predominated (77%); for 7 bleached corals, depletion of zooxanthellae from the gastrodermis made up a majority of microscopic diagnoses (57%); and for growth anomalies other than umbonate, hyperplasia of the basal body wall was the most common microscopic finding (63%). For the remainder of the gross lesions, no single microscopic finding constituted >50% of the total. Host response varied with the agent present on histology. Fragmentation of tissues was most often associated with algae (60%), whereas necrosis dominated (53%) for fungi. Two newly documented potentially symbiotic tissue-associated metazoans were seen in Porites and Montipora. Findings of multiple potential etiologies for a given gross lesion highlight the importance of incorporating histopathology in coral disease surveys. This study also expands the range of corals infected with cell-associated microbial aggregates. © The Author(s) 2015.

The authors documented gross and microscopic morphology of lesions in corals on 7 islands spanning western, southern, and eastern Micronesia, sampling 76 colonies comprising 30 species of corals among 18 genera, with Acropora, Porites, and Montipora dominating. Tissue loss comprised the majority of gross lesions sampled (41%), followed by discoloration (30%) and growth anomaly (29%). Of 31 cases of tissue loss, most lesions were subacute (48%), followed by acute and chronic (26% each). Of 23 samples with discoloration, most were dark discoloration (40%), with bleaching and other discoloration each constituting 30%. Of 22 growth anomalies, umbonate growth anomalies composed half, with exophytic, nodular, and rugose growth anomalies composing the remainder. On histopathology, for 9 cases of dark discoloration, fungal infections predominated (77%); for 7 bleached corals, depletion of zooxanthellae from the gastrodermis made up a majority of microscopic diagnoses (57%); and for growth anomalies other than umbonate, hyperplasia of the basal body wall was the most common microscopic finding (63%). For the remainder of the gross lesions, no single microscopic finding constituted >50% of the total. Host response varied with the agent present on histology. Fragmentation of tissues was most often associated with algae (60%), whereas necrosis dominated (53%) for fungi. Two newly documented potentially symbiotic tissue-associated metazoans were seen in Porites and Montipora. Findings of multiple potential etiologies for a given gross lesion highlight the importance of incorporating histopathology in coral disease surveys. This study also expands the range of corals infected with cell-associated microbial aggregates.

Dysplastic nevi with severe atypia (severely dysplastic nevi [SDN]) are frequently re-excised because of the concern that these lesions may in fact represent early melanoma. Data on long-term follow-up of these patients are limited. We sought to determine the rate of subsequent melanoma development in patients with SDN who underwent re-excision versus those who did not and to determine factors associated with decision to re-excise. A retrospective single institutional study was conducted with 451 adult patients (mean age 41.3 years) with SDN biopsied between November 1994 and November 2004, with clinical follow-up of at least 5 years. In 451 patients with SDN, re-excision was performed on 36.6%. Two melanomas were diagnosed in the re-excision specimens. Subsequent metastatic melanoma developed in 7 patients, all of whom had a history of melanoma. Margin comments influenced decision to re-excise. This was a retrospective study at a single institution. Re-excision of all SDN may not be necessary. Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc.

Repair of DNA-polypeptide crosslinks by human excision nuclease

NASA Astrophysics Data System (ADS)

Reardon, Joyce T.; Sancar, Aziz

2006-03-01

DNA-protein crosslinks are relatively common DNA lesions that form during the physiological processing of DNA by replication and recombination proteins, by side reactions of base excision repair enzymes, and by cellular exposure to bifunctional DNA-damaging agents such as platinum compounds. The mechanism by which pathological DNA-protein crosslinks are repaired in humans is not known. In this study, we investigated the mechanism of recognition and repair of protein-DNA and oligopeptide-DNA crosslinks by the human excision nuclease. Under our assay conditions, the human nucleotide excision repair system did not remove a 16-kDa protein crosslinked to DNA at a detectable level. However, 4- and 12-aa-long oligopeptides crosslinked to the DNA backbone were recognized by some of the damage recognition factors of the human excision nuclease with moderate selectivity and were excised from DNA at relatively efficient rates. Our data suggest that, if coupled with proteolytic degradation of the crosslinked protein, the human excision nuclease may be the major enzyme system for eliminating protein-DNA crosslinks from the genome. damage recognition | nucleotide excision repair

Excision of Sleeping Beauty transposons: parameters and applications to gene therapy

A major problem in gene therapy is the determination of the rates at which gene transfer has occurred. Our work has focused on applications of the Sleeping Beauty (SB) transposon system as a non-viral vector for gene therapy. Excision of a transposon from a donor molecule and its integration into a cellular chromosome are catalyzed by SB transposase. In this study, we used a plasmid-based excision assay to study the excision step of transposition. We used the excision assay to evaluate the importance of various sequences that border the sites of excision inside and outside the transposon in order to determine the most active sequences for transposition from a donor plasmid. These findings together with our previous results in transposase binding to the terminal repeats suggest that the sequences in the transposon-junction of SB are involved in steps subsequent to DNA binding but before excision, and that they may have a role in transposase–transposon interaction. We found that SB transposons leave characteristically different footprints at excision sites in different cell types, suggesting that alternative repair machineries operate in concert with transposition. Most importantly, we found that the rates of excision correlate with the rates of transposition. We used this finding to assess transposition in livers of mice that were injected with the SB transposon and transposase. The excision assay appears to be a relatively quick and easy method to optimize protocols for delivery of genes in SB transposons to mammalian chromosomes in living animals. PMID:15133768

To assess if combined fluorescence- and radio-guided occult lesion localization (hybrid ROLL) is feasible in patients scheduled for surgical resection of non-palpable (18)F-FDG-avid lesions on PET/CT. Four patients with (18)F-FDG-avid lesions on follow-up PET/CT that were not palpable during physical examination but were suspected to harbor metastasis were enrolled. Guided by ultrasound, the hybrid tracer indocyanine green (ICG)-(99m)Tc-nanocolloid was injected centrally in the target lesion. SPECT/CT imaging was used to confirm tracer deposition. Intraoperatively, lesions were localized using a hand-held gamma ray detection probe, a portable gamma camera, and a fluorescence camera. After excision, the gamma camera was used to check the wound bed for residual activity. A total of six (18)F-FDG-avid lymph nodes were identified and scheduled for hybrid ROLL. Comparison of the PET/CT images with the acquired SPECT/CT after hybrid tracer injection confirmed accurate tracer deposition. No side effects were observed. Combined radio- and fluorescence-guidance enabled localization and excision of the target lesion in all patients. Five of the six excised lesions proved tumor-positive at histopathology. The hybrid ROLL approach appears to be feasible and can facilitate the intraoperative localization and excision of non-palpable lesions suspected to harbor tumor metastases. In addition to the initial radioguided detection, the fluorescence component of the hybrid tracer enables high-resolution intraoperative visualization of the target lesion. The procedure needs further evaluation in a larger cohort and wider range of malignancies to substantiate these preliminary findings. Copyright © 2016 Elsevier España, S.L.U. y SEMNIM.

BACKGROUND: Preoperative skin antisepsis is routine practice. We compared alcoholic chlorhexidine with aqueous chlorhexidine for skin antisepsis to prevent surgical site infection after minor skin excisions in general practice. METHODS: We conducted this prospective, multicentre, randomized controlled trial in 4 private general practices in North Queensland, Australia, from October 2015 to August 2016. Consecutive adult patients presenting for minor skin excisions were randomly assigned to undergo preoperative skin antisepsis with 0.5% chlorhexidine in 70% ethanol (intervention) or 0.5% chlorhexidine aqueous solution (control). Our primary outcome was surgical site infection within 30 days of excision. We also measured the incidence of adverse reactions. RESULTS: A total of 916 patients were included in the study: 454 underwent antisepsis with alcoholic chlorhexidine and 462 with aqueous chlorhexidine. Of these, 909 completed follow-up. In the intention-to-treat analysis of cases available at follow-up, there was no significant difference in the incidence of surgical site infection between the alcoholic chlorhexidine arm (5.8%, 95% confidence interval [CI] 3.6% to 7.9%) and the aqueous chlorhexidine arm (6.8%, 95% CI 4.5% to 9.1%). The attributable risk reduction was 0.010 (95% CI –0.021 to 0.042), the relative risk was 0.85 (95% CI 0.51 to 1.41), and the number needed to treat to benefit was 100. Per protocol and sensitivity analyses produced similar results. The incidence of adverse reactions was low, with no difference between groups (p = 0.6). INTERPRETATION: There was no significant difference in efficacy between alcoholic and aqueous chlorhexidine for the prevention of surgical site infection after minor skin excisions in general practice.

2015-07-01

In this work, we present relatively long-term results of femoral head fractures with a specific focus on Pipkin type I fractures. Fifty-nine femoral head fractures were treated according to modified Pipkin's classification as follows: type I, small fragment distal to the fovea centralis (FC); type II, large fragment distal to the FC; type III, large fragment proximal to the FC; type IV, comminuted fracture. There were 15 cases of type I, 28 of type II, 9 of type III, and 7 of type IV fractures. Conservative treatment with skeletal traction was performed in 4 type II cases, excision of the fragment in 15 type I and 10 type II cases, fixation of the fragment in 14 type II and all 9 type III cases, and total hip replacement in all 7 type IV cases. The overall clinical and radiographic outcomes were evaluated using previously published criteria, focusing on the results in Pipkin type I fractures with relatively large fragments. Based on Epstein criteria, in type II fractures, excellent or good clinical results were seen in 6 of 10 patients (60.0 %) treated by excision of the fragment and 12 of 14 patients (85.7 %) treated by internal fixation (p = 0.05). Also, excellent or good radiologic results were seen in 4 of 10 (40.0 %) patients treated by excision of the fragment and 12 of 14 (85.7 %) patients treated by internal fixation (p = 0.03). Even in Pipkin type I fractures, if the fragment is large (modified Pipkin type II), early reduction and internal fixation can produce good results.

Subtalar Coalitions: Does the Morphology of the Subtalar Joint Involvement Influence Outcomes After Coalition Excision?

PubMed

Mahan, Susan T; Prete, Victoria I; Spencer, Samantha A; Kasser, James R; Bixby, Sarah D

Posteromedial subtalar (PMST) coalitions are a recently described anatomic subtype of tarsal coalitions. We compared with clinical patient-based outcomes of patients with PMST and standard middle facet (MF) coalitions who had undergone surgical excision of their coalition. The included patients had undergone surgical excision of a subtalar tarsal coalition, preoperative computed tomography (CT), and patient-based outcomes measures after surgery (including the American Orthopaedic Foot and Ankle Society [AOFAS] scale and University of California, Los Angeles [UCLA], activity score). Blinded analysis of the preoperative CT scan findings determined the presence of a standard MF versus a PMST coalition. The perioperative factors and postoperative outcomes between the MF and PMST coalitions were compared. A total of 51 feet (36 patients) were included. The mean follow-up duration was 2.6 years after surgery. Of the 51 feet, 15 (29.4%) had a PMST coalition and 36 (70.6%) had an MF coalition. No difference was found in the UCLA activity score; however, the mean AOFAS scale score was higher for patients with PMST (95.7) than for those with MF (86.5; p = .018). Of the patients with a PMST, none had foot pain limiting their activities at the final clinical follow-up visit. However, in the group with an MF subtalar coalition, 10 (27.8%) had ongoing foot pain limiting activity at the final follow-up visit (p = .024). Compared with MF subtalar tarsal coalitions, patients with PMST coalitions showed significantly improved clinical outcomes after excision. Preoperative identification of the facet morphology can improve patient counseling and expectations after surgery. Copyright © 2017 American College of Foot and Ankle Surgeons.

1991-02-01

The purpose of this study is to compare the rate of local complications resulting from radioiodine ablation of thyroid cancer in patients with a residual intact thyroid lobe to that in patients who had more extensive surgical treatment prior to radioiodine administration. We retrospectively studied 59 patients who had received 131I between 1979 and 1989. The patients were divided into two groups, depending on the extent of their previous surgical thyroid excision. Group 1 comprised 10 patients with a lobectomy or hemithyroidectomy before the ablative radioiodine dose, and Group 2 comprised 49 patients with more extensive thyroid excision (near-total ormore » subtotal thyroidectomy) before the radioiodine treatment. Sixty percent of the 10 patients in Group 1 experienced some degree of neck pain or tenderness following radioiodine ablation of their residual thyroid. In one case, the local reaction was very severe and accompanied by the development of transient hyperthyroidism. There was only a 6% local complication rate in the patients who had undergone more extensive thyroid excision before ablative therapy (p less than 0.001), and none had a severe reaction. Patients with only unilateral surgical excision before radioiodine therapy have a higher rate of local complications than do patients treated with more extensive surgery prior to radioiodine ablation. If radioiodine is to be employed in such patients, they should be informed of this possible complication. Since evidence supports a dose effect in the pathogenesis of the complications, we recommend using a dose of less than 30 mCi for the initial ablation in these patients even though it may be necessary to repeat this dose to complete thyroid ablation.« less

2017-02-01

Accessory breasts have received little attention in the surgical fields, although the condition is quite common in the female population, with 2-6% of women suffering from it. Its convexity and cyclic pain make women feel embarrassed and uncomfortable, so patients often desire surgical excision to improve their appearances and to remove the pain. A total of 967 patients who had been treated by an excision of accessory breast tissue with liposuction using minimal incision from September 2013 to Dec 2015 at the Damsoyu Hospital were analyzed for clinical factors retrospectively. All 967 patients were female. There were 514 (53.2%) unmarried patients and 453 (46.8%) married patients. The major clinical manifestation was the problem in the appearance with cyclic pain in both unmarried and married groups (82.7 vs. 87.9%). Three types of accessory breasts were observed: 779 (80.6%) breast tissue only in axillae, 182 (18.8%) breast tissue with accessory nipple, and 6 (0.6%) breast tissue with accessory nipple-areolar complex. The mean operation time was 58 min. All cyclic axillar pain in our cases was resolved after the operation. Postoperative complications developed in 160 patients (16.55%). Among them, seroma after operation was the most common (11.27%). In our study, 95.65% of the patients were satisfied with the cosmetic outcomes. The surgical excision of accessory breasts with liposuction through the minimal incision is a safe and effective method to make women feel comfortable in clinical manifestations and be satisfied with their cosmetic axillar line.

This study aims to report our multicenter experience with diagnosis, management, and prognosis of anorectal gastrointestinal stromal tumors (GIST). We retrospectively reviewed cases treated and/or followed up at our institutions in the period 2000-2011. Fifteen patients were identified (eight men and seven women; mean age, 55 years). Presenting symptoms were rectal/perirectal (eight), rectovaginal space (four), or retrovesical/prostatic (three) mass. Primary surgical treatment was local excision (six), deep anterior resection (eight), and palliative diagnostic excision (one). Tumor mean size was 4.8 cm. All but two cases were high risk (Miettinen and Lasota, Semin Diagn Pathol 23:70-83, 2006). R0 resection was achieved in 46% of cases: one of six local excisions vs. five of seven deep anterior resection (16 vs. 71%, respectively). All three cases who received total mesorectal excision had R0. Non-R0 status was mainly due to opening of tumor capsule at surgery (Rx). Seven of 14 patients (50%) developed ≥1 pelvic local recurrences at a mean period of 48.4 months (mean follow-up, 61.6 months). Only two patients developed distant metastasis (adrenal, liver, and peritoneal). Recurrences developed after Rx (three), R1 (two), and unknown R-status (two). Successful mutational analysis in 13 patients revealed KIT mutations in all (10 exon 11, 2 exon 9, and 1 exon 13). Our results confirm the high local recurrence rate of anorectal GISTs (50%) which correlates with the common practice of suboptimal oncological primary tumor resection (Rx or R1 = 7/13). This uncommon subset of GISTs needs more standardized oncological surgical approach to minimize the propensity for local disease recurrence.

The objective of this study was to evaluate the wound healing potential of L-glutamine in laboratory rats using excision and incision wound models. Excision wounds of size 500 mm(2) and depth 2 mm were made on the dorsal portion of male Wistar rats (230-250 g) and were used for the study of oral L-glutamine (1 g/kg) treatment on the rate of contraction of wound and epithelisation. Histological evaluation of wound tissue was also performed. Six-centimetre-long two linear-paravertebral incisions in male Wistar rats (230-250 g) were used to study the effect of L-glutamine (1 g/kg, p.o.) treatment on tensile strength, total protein and hydroxyproline content in the incision model. Oral administration of L-glutamine (1 g/kg) significantly decreased wound area, epithelisation period and wound index, whereas the rate of wound contraction significantly increased (P < 0·001) when compared with vehicle control rats in the excision wound model. Tensile strength, hydroxyproline content and protein level were significantly increased (P < 0·001) in L-glutamine (1 g/kg, p.o.)-treated rats when compared with vehicle control rats in the incision wound model. Histological evaluation of wound tissue from L-glutamine (1 g/kg, p.o.)-treated rats showed complete epithelialisation with new blood vessel formation and high fibrous tissues in the excision wound model. In conclusion, oral administration of l-glutamine (1 g/kg) promotes wound healing by acting on various stages of wound healing such as collagen synthesis, wound contraction and epithelialisation. © 2014 The Authors.

Although tumor resection is the mainstay of treatment for localized neuroblastoma, there are no established guidelines indicating which patients should be operated on immediately and which should undergo surgery after tumor reduction with chemotherapy. In an effort to develop such guidelines, the LNESG1 study defined surgical risk factors (SRFs) based on the imaging characteristics. A total of 905 patients with suspected localized neuroblastoma were registered by 10 European countries between January 1995 and October 1999; 811 of 905 patients were eligible for this analysis. Information on SRFs was obtained for 719 of 811 patients; 367 without and 352 with SRFs. Of these 719 patients, 201 patients (four without and 197 with SRFs) underwent biopsy only. An attempt at tumor excision was made in 518 patients: 363 of 367 patients without and 155 of 352 patients with SRFs (98.9% v 44.0%). Complete excision was achieved in 271 of 363 patients without and in 72 of 155 patients with SRF (74.6% v 46.4%), near-complete excision was achieved in 81 and 61 patients (22.3% v 39.3%), and incomplete excision was achieved in 11 and 22 patients (3.0% v 14.2%), respectively. There were two surgery-related deaths. Nonfatal surgery-related complications occurred in 45 of 518 patients (8.7%) and were less frequent in patients without SRFs (5.0% v 17.4%). Associated surgical procedures were also less frequent in patients without SRFs (1.6% v 9.7%). The adoption of SRFs as predictors of adverse surgical outcome was validated because their presence was associated with lower complete resection rate and greater risk of surgery-related complications. Additional studies aiming to better define the surgical approach to localized neuroblastoma are warranted.

Beal, Kathryn; McCormick, Beryl; Zelefsky, Michael J.

2007-09-01

Purpose: To evaluate the cosmetic outcome of patients treated with wide local excision and intraoperative radiotherapy for early-stage breast cancer. Methods and Materials: A total of 50 women were treated on a pilot study to evaluate the feasibility of intraoperative radiotherapy at wide local excision. The eligibility criteria included age >60, tumor size {<=}2.0 cm, clinically negative lymph nodes, and biopsy-established diagnosis. After wide local excision, a custom breast applicator was placed in the excision cavity, and a dose of 20 Gy was prescribed to a depth of 1 cm. After 18 patients were treated, the dose was constrained laterallymore » to 18 Gy. The cosmetic outcome was evaluated by photographs at baseline and at 6 and 12 months postoperatively. Four examiners graded the photographs for symmetry, edema, discoloration, contour, and scarring. The grades were evaluated in relationship to the volume of irradiated tissue, tumor location, and dose at the lateral aspects of the cavity. Results: The median volume of tissue receiving 100% of the prescription dose was 47 cm{sup 3} (range, 20-97 cm{sup 3}). Patients with {<=}47 cm{sup 3} of treated tissue had better cosmetic outcomes than did the women who had >47 cm{sup 3} of treated tissue. Women who had received 18 Gy at the lateral aspects of their cavities had better cosmetic outcomes than did women who had received 20 Gy at the lateral aspects. When comparing the 6- and 12-month results, the scores remained stable for 63%, improved for 17%, and worsened for 20%. Conclusion: Intraoperative radiotherapy appears feasible for selected patients. A favorable cosmetic outcome appears to be related to a smaller treatment volume. The cosmetic outcome is acceptable, although additional follow-up is necessary.« less

Extra-dimensional Demons: a method for incorporating missing tissue in deformable image registration.

A deformable registration method capable of accounting for missing tissue (e.g., excision) is reported for application in cone-beam CT (CBCT)-guided surgical procedures. Excisions are identified by a segmentation step performed simultaneous to the registration process. Tissue excision is explicitly modeled by increasing the dimensionality of the deformation field to allow motion beyond the dimensionality of the image. The accuracy of the model is tested in phantom, simulations, and cadaver models. A variant of the Demons deformable registration algorithm is modified to include excision segmentation and modeling. Segmentation is performed iteratively during the registration process, with initial implementation using a threshold-based approach to identify voxels corresponding to "tissue" in the moving image and "air" in the fixed image. With each iteration of the Demons process, every voxel is assigned a probability of excision. Excisions are modeled explicitly during registration by increasing the dimensionality of the deformation field so that both deformations and excisions can be accounted for by in- and out-of-volume deformations, respectively. The out-of-volume (i.e., fourth) component of the deformation field at each voxel carries a magnitude proportional to the excision probability computed in the excision segmentation step. The registration accuracy of the proposed "extra-dimensional" Demons (XDD) and conventional Demons methods was tested in the presence of missing tissue in phantom models, simulations investigating the effect of excision size on registration accuracy, and cadaver studies emulating realistic deformations and tissue excisions imparted in CBCT-guided endoscopic skull base surgery. Phantom experiments showed the normalized mutual information (NMI) in regions local to the excision to improve from 1.10 for the conventional Demons approach to 1.16 for XDD, and qualitative examination of the resulting images revealed major differences: the conventional Demons approach imparted unrealistic distortions in areas around tissue excision, whereas XDD provided accurate "ejection" of voxels within the excision site and maintained the registration accuracy throughout the rest of the image. Registration accuracy in areas far from the excision site (e.g., > ∼5 mm) was identical for the two approaches. Quantitation of the effect was consistent in analysis of NMI, normalized cross-correlation (NCC), target registration error (TRE), and accuracy of voxels ejected from the volume (true-positive and false-positive analysis). The registration accuracy for conventional Demons was found to degrade steeply as a function of excision size, whereas XDD was robust in this regard. Cadaver studies involving realistic excision of the clivus, vidian canal, and ethmoid sinuses demonstrated similar results, with unrealistic distortion of anatomy imparted by conventional Demons and accurate ejection and deformation for XDD. Adaptation of the Demons deformable registration process to include segmentation (i.e., identification of excised tissue) and an extra dimension in the deformation field provided a means to accurately accommodate missing tissue between image acquisitions. The extra-dimensional approach yielded accurate "ejection" of voxels local to the excision site while preserving the registration accuracy (typically subvoxel) of the conventional Demons approach throughout the rest of the image. The ability to accommodate missing tissue volumes is important to application of CBCT for surgical guidance (e.g., skull base drillout) and may have application in other areas of CBCT guidance.

Excisions are modeled explicitly during registration by increasing the dimensionality of the deformation field so that both deformations and excisions can be accounted for by in- and out-of-volume deformations, respectively. The out-of-volume (i.e., fourth) component of the deformation field at each voxel carries a magnitude proportional to the excision probability computed in the excision segmentation step. The registration accuracy of the proposed “extra-dimensional” Demons (XDD) and conventional Demons methods was tested in the presence of missing tissue in phantom models, simulations investigating the effect of excision size on registration accuracy, and cadaver studies emulating realistic deformations and tissue excisions imparted in CBCT-guided endoscopic skull base surgery. Results: Phantom experiments showed the normalized mutual information (NMI) in regions local to the excision to improve from 1.10 for the conventional Demons approach to 1.16 for XDD, and qualitative examination of the resulting images revealed major differences: the conventional Demons approach imparted unrealistic distortions in areas around tissue excision, whereas XDD provided accurate “ejection” of voxels within the excision site and maintained the registration accuracy throughout the rest of the image. Registration accuracy in areas far from the excision site (e.g., > ∼5 mm) was identical for the two approaches. Quantitation of the effect was consistent in analysis of NMI, normalized cross-correlation (NCC), target registration error (TRE), and accuracy of voxels ejected from the volume (true-positive and false-positive analysis). The registration accuracy for conventional Demons was found to degrade steeply as a function of excision size, whereas XDD was robust in this regard. Cadaver studies involving realistic excision of the clivus, vidian canal, and ethmoid sinuses demonstrated similar results, with unrealistic distortion of anatomy imparted by conventional Demons and accurate ejection and deformation for XDD. Conclusions: Adaptation of the Demons deformable registration process to include segmentation (i.e., identification of excised tissue) and an extra dimension in the deformation field provided a means to accurately accommodate missing tissue between image acquisitions. The extra-dimensional approach yielded accurate “ejection” of voxels local to the excision site while preserving the registration accuracy (typically subvoxel) of the conventional Demons approach throughout the rest of the image. The ability to accommodate missing tissue volumes is important to application of CBCT for surgical guidance (e.g., skull base drillout) and may have application in other areas of CBCT guidance.

Cervical cystic lymphangioma (CCL) is a rare and benign tumour involving congenital and cystic abnormalities derived from lymphatic vessels. The most accepted treatment continues to be surgical excision. However, when this infiltrates vital neurovascular neck structures, complete excision is difficult and if only partial, the recurrence rate is very high. The most frequently used alternative treatment is to inject sclerosants into the lesion. The use of these techniques has reported good results in children; however, there are few references thereof with regard to adults. We are reporting on a cervical cystic lymphangioma in a male aged 22, treated with an intra-lesion injection of 20 cc with 0.01 mg/cc dilution of OK-432 (picibanil) in physiological serum. Sole complications were fever and local reaction where the solution was injected. One month after treatment the lymphangioma had totally remitted and sixteen months later continues in remittance.

Olfactory neuroblastoma is a rare malignancy of the nasal cavity in dogs that is thought to arise from specialised sensory neuroendocrine olfactory cells derived from the neural crest. An 8-year-old dog was presented for reclusiveness and pacing. On CT and MRI, a contract-enhancing mass was disclosed within the rostral fossa, extending caudally from the cribriform plate into the left nasal sinus. Surgical excision was performed and the diagnosis was histological grade III (Hyams grading scheme) olfactory neuroblastoma. Based on human CT criteria this was high stage (modified Kadish stage C). Surgical excision was incomplete and was followed by curative-intent radiation therapy using a linear accelerator to a total dose of 48 Gy. The dog survived 20 months after diagnosis. Although olfactory neuroblastoma is a rare tumour in dogs, aggressive local therapy may allow for prolonged survival, even when the tumour is advanced. © 2017 Australian Veterinary Association.

Disease activity, quality of life and indirect costs of reduced productivity at work, generated by Polish patients with ankylosing spondylitis.

The aim of the study was to investigate the association between activity of ankylosing spondylitis (AS) and decrease in quality of life as well as productivity loss of affected patients in a specified group of patients in the Polish setting. An questionnaire survey was conducted using the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) to assess disease activity, as well as the Work Productivity and Activity Impairment Questionnaires to assess productivity loss; quality of life was presented as utility calculated using the EuroQol 5 questionnaire and also measured on a visual analogue scale (VAS). Indirect costs were assessed with the human capital approach implying gross domestic product per capita or gross value added per worker in Poland in 2014 and were expressed in Polish zlotys (PLN) as well as in euros. Correlation was presented using Spearman's rank correlation coefficient. We performed our analysis based on 78 full questionnaires collected. A mean BASDAI score of 5.91 in the analysed group of patients was detected and mean utility of 0.5135 was observed. Average quality of life measured on the visual analogue scale was 46.55. Mean number of days off work was 45.26 days per year and mean on-the-job productivity loss was 49.29%. Average annual indirect costs per patient were €4241 (17 686 PLN) calculated using gross domestic product and €10 172 (42 417 PLN) estimated using gross value added. Total productivity loss was significantly correlated with disease activity (strong correlation of 0.6005) and utility (moderate correlation of -0.3698). Ankylosing spondylitis causes a great decrease in quality of life as well as patients' productivity loss associated with both absenteeism and presenteeism. The greater the disease activity is, the lower is the utility, the lower is the quality of life measured on the VAS, and the greater are the total annual indirect costs. Total indirect costs were negatively correlated with utility; although the association was moderate, it was significant.

Ceramic coatings have been used in metal-on-polyethylene (MOP) hips to reduce the risk of wear and also infection; the clinical efficacy of this remains unclear. This retrieval study sought to better understand the performance of coated bearing surfaces. Forty-three coated MOP components were analysed post-retrieval for evidence of coating loss and gross polyethylene wear. Coating loss was graded using a visual semi-quantitative protocol. Evidence of gross polyethylene wear was determined by radiographic analysis and visual inspection of the retrieved implants. All components with gross polyethylene wear (n = 10) were revised due to a malfunctioning acetabular component; 35 % (n = 15) of implants exhibited visible coating loss and the incidence of polyethylene wear in samples with coating loss was 54 %, significantly (p = 0.02) elevated compared to samples with intact coatings (14 %). In this study we found evidence of coating loss on metal femoral heads which was associated with increased wear of the corresponding polyethylene acetabular cups.

Unexpected malignancy is common in major salivary gland tumors due to variability of workup, creating challenging treatment decisions. The purpose of this study was to define treatment-related outcomes for patients with incompletely treated major salivary gland tumors. A retrospective cohort study was completed of patients with incompletely treated major salivary gland tumors. Tumor burden at presentation was established and treatment categorized. The Cox Proportional Hazards model was used to determine predictors of survival and failure. Of the 440 included patients, patients with gross residual or metastatic disease had a worse overall survival (OS; P < .001). Presentation status was an independent predictor of OS on multivariate analysis (gross residual disease adjusted hazard ratio [HR adjusted ] 2.55; 95% confidence interval [CI] 1.20-5.30; metastatic disease HR adjusted 9.53; 95% CI 3.04-27.06). Failure to achieve gross total resection during initial surgery resulted in worse OS. Adequate preoperative planning is required for initial surgical management to optimize tumor control and survival. © 2018 Wiley Periodicals, Inc.

The purpose of this study was to report the surgical treatment experience of patients with amniotic constriction bands (ACB) over a 35-year interval and detail consequential limb deformities with emphasis on hands and upper extremities, along with the nature and frequency of their surgical treatment methods. Fifty-one patients were identified; 26 were males and 25 females. The total number of deformities was listed. The total number of operations, individual procedures, and operations plus procedures that were done for each patient and their frequency were recorded. The total number of operations was 117, and total number of procedures was 341. More procedures were performed on the upper extremity (85%) than the lower extremity (15%). Including the primary deformity ACB, 16 different hand deformities secondary to ACB were encountered. Sixteen different surgical methods for the upper extremity were utilized; a primary procedure for ACB and secondary reconstructions for all secondary deformities. Average age at the time of the first procedure was 9.3 months. The most common procedures performed, in order of frequency, were excision of ACB plus Z-plasty, release of partial syndactyly, release of fenestrated syndactyly, full-thickness skin grafts, resection of digital bony overgrowth from amputation stumps, and deepening of first and other digital web spaces. Many hand and upper extremity deformities secondary to ACB are encountered. Children with ACB may require more than one operation including multiple procedures. Numerous surgical methods of reconstruction for these children's secondary deformities are necessary in addition to the customary primary procedure of excision of ACB and Z-plasty.

Previous studies have compared the outcomes after open and endoscopic excision of an os trigonum in patients of mixed professions. No studies have compared the differences in outcomes between the 2 procedures in elite ballet dancers. From October 2005 to February 2010, 35 professional ballet dancers underwent excision of a symptomatic os trigonum of the ankle after a failed period of nonoperative treatment. Of the 35 patients, 13 (37.1%) underwent endoscopic excision and 22 (62.9%) open excision. We compared the outcomes, complications, and time to return to dancing. The open excision group experienced a significantly greater incidence of flexor hallucis longus tendon decompression compared with the endoscopic group. The endoscopic release group returned to full dance earlier at a mean of 9.8 (range 6.5 to 16.1) weeks and those undergoing open excision returned to full dance at a mean of 14.9 (range 9 to 20) weeks (p = .001). No major complications developed in either group, such as deep infection or nerve or vessel injury. We have concluded that both techniques are safe and effective in the treatment of symptomatic os trigonum in professional ballet dancers. Endoscopic excision of the os trigonum offers a more rapid return to full dance compared with open excision. Copyright © 2016 American College of Foot and Ankle Surgeons. Published by Elsevier Inc.

Little is known about anorectal function and quality of life after chemoradiation followed by local excision, which is an alternative to total mesorectal excision for selected patients with early rectal cancer. The purpose of this study was to prospectively assess anorectal function and health-related quality of life of patients with T2N0 rectal cancer who were treated with an alternative approach. This was a prospective, phase II trial. The study was multicentric (American College of Surgeons Oncology Group trial Z6041). Patients with stage cT2N0 rectal adenocarcinomas were treated with an oxaliplatin/capecitabine-based chemoradiation regimen followed by local excision. Anorectal function and quality of life were assessed at enrollment and 1 year postoperatively with the Fecal Incontinence Severity Index, Fecal Incontinence Quality of Life scale, and Functional Assessment of Cancer Therapy-Colorectal Questionnaire. Results were compared, and multivariable analysis was performed to identify predictors of outcome. Seventy-one patients (98%) were evaluated at enrollment and 66 (92%) at 1 year. Compared with baseline, no significant differences were found on Fecal Incontinence Severity Index scores at 1 year. Fecal Incontinence Quality of Life results were significantly worse in the lifestyle (p < 0.001), coping/behavior (p < 0.001), and embarrassment (p = 0.002) domains. There were no differences in the Functional Assessment of Cancer Therapy overall score, but the physical well-being subscale was significantly worse and emotional well-being was improved after surgery. Treatment with the original chemoradiation regimen predicted worse depression/self-perception and embarrassment scores in the Fecal Incontinence Quality of Life, and male sex was predictive of worse scores in the Functional Assessment of Cancer Therapy overall score and trial outcome index. Small sample size, relatively short follow-up, and absence of information before cancer diagnosis were study limitations. Chemoradiation followed by local excision had minimal impact on anorectal function 1 year after surgery. Overall quality of life remained stable, with mixed effects on different subscales. This information should be used to counsel patients about expected outcomes.

In addition to benefits for bone health, vitamin D is implicated in muscle function in children and adults. To determine if vitamin D dosage positively correlated with gross motor development at 3 and 6 months of age. We hypothesized that higher doses would be associated with higher scores for gross motor skills. A consecutive sample of 55 healthy, term, and breastfed infants from Montreal, Canada were recruited from a randomized trial of vitamin D supplementation between 2009 and 2012. Infants were randomized to 400 International Units (IU) (n = 19), 800 IU (n = 18) or 1,200 IU (n = 18) vitamin D3/day. Motor performance at 3 and 6 months was quantified by the Alberta Infant Motor Scale (AIMS). Plasma vitamin D3 metabolites were measured by tandem mass spectrometry. AIMS scores did not differ at 3 months. However, total AIMS scores and sitting subscores were significantly higher at 6 months in infants receiving 400 IU/day compared to 800 IU/day and 1,200 IU/day groups (p < .05). There were weak negative correlations with length and C-3 epimer of 25(OH)D. In contrast to our hypothesis, gross motor achievements were significantly higher in infants receiving 400 IU/day vitamin D. Our findings also support longer infants being slightly delayed.

Objective Being overweight makes physical movement more difficult. Our aim was to investigate the association between body composition and motor performance in preschool children. Methods A total of 476 predominantly normal-weight preschool children (age 3.9 ± 0.7 years; m/f: 251/225; BMI 16.0 ± 1.4 kg/m2) participated in the Swiss Preschoolers' Health Study (SPLASHY). Body composition assessments included skinfold thickness, waist circumference (WC), and BMI. The Zurich Neuromotor Assessment (ZNA) was used to assess gross and fine motor tasks. Results After adjustment for age, sex, socioeconomic status, sociocultural characteristics, and physical activity (assessed with accelerometers), skinfold thickness and WC were both inversely correlated with jumping sideward (gross motor task β-coefficient −1.92, p = 0.027; and −3.34, p = 0.014, respectively), while BMI was positively correlated with running performance (gross motor task β-coefficient 9.12, p = 0.001). No significant associations were found between body composition measures and fine motor tasks. Conclusion The inverse associations between skinfold thickness or WC and jumping sideward indicates that children with high fat mass may be less proficient in certain gross motor tasks. The positive association between BMI and running suggests that BMI might be an indicator of fat-free (i.e., muscle) mass in predominately normal-weight preschool children. PMID:28934745

Hemangioblastomas [75% sporadic, 25% with Von Hippel Lindau (VHL) disease] are highly vascular, benign lesions. The surgical nuances, management, and complication avoidance in brain-stem hemangioblastomas (BHs) have been studied. Over 18 years, 27(mean age: 29 years; range 15-60 years) consecutive cases of BH underwent microsurgical excision. All patients were assessed clinico-radiologically for neurological deficits and screened for VHL disease. Outcome of the patients was based on Karnofsky Performance Status scale (KPS). 12 out of 19 (70.4%) patients with hydrocephalus underwent a cerebrospinal fluid (CSF) diversion procedure. Lower cranial nerve palsy was present in 10 (37%) patients and motor weakness in 13 (48%). The tumours [mean size 3.34 ± 1.06 cm, range: 1.4-5.5 cm; 11 solid, rest solid-cystic; 18 (66.7%) subpial and 9 (33.33%) intramedullary] were divided into four categories based on size: A: <2 cm (n = 5,18.5%); B: 2-3 cm (n = 10,37%); C: 3-4 cm (n = 6,22.2%); D: >4 cm (n = 6,22.2%). Their location was at posterior cervicomedullary junction (n = 12); pontomedullary junction (n = 7); pons (n = 3), medulla (n = 3) and ponto-mesencephalic region (n = 2). Multiple flow voids were seen in >50% patients with tumour >2 cm. 5 patients had syringomyelia; and, 8 had diffuse cervical cord expansion. Two patients with a large vascular tumour underwent preoperative embolization. Six patients had VHL disease; one underwent bilateral adrenalectomy for refractory hypertension; and, the another, nephrectomy for renal cell carcinoma. Twenty-six patients underwent a midline suboccipital craniectomy; and, 1 with a cerebellopontine angle tumour, a retromastoid craniectomy. 15 patients underwent total excision; 10 patients, near-total (<10% remaining) excision, and 2 patients, a subtotal (>10% remaining)) excision. Three patients (2 with VHL disease) expired due to exsanguinating hemorrhage, spreading venous thrombosis and aspiration pneumonitis, respectively. At follow-up visit (median: 25 ± interquartile range 2-56months), 17 patients had improved KPS, 4 remained in same status and 3 (recently operated, on tracheostomy) had worsened KPS. Significant improvement is achievable in neurological status in patients following successful extirpation of a brain-stem hemangioblastoma, despite a turbulent perioperative period. Leaving tumour capsule adherent to the brain-stem often helps in preserving brain-stem function. Postoperatively, the patients should be monitored for their respiratory and lower cranial nerve status to prevent aspiration pneumonitis.

Dimer excision in Escherichia coli in the presence of caffeine

The observation that polA1 and recL152 mutations result in both slow pyrimidine dimer excision and large repair patch size leads to the hypothesis that patch size is directly related to the rate of excision. In this study caffeine, a known inhibitor of excision repair, was used to examine the extent of correlation between excision rate and patch size by measuring patch size in the presence of several concentrations of caffeine. Both the rate of excision and the resistance to ultraviolet radiation were reduced with increasing concentrations of caffeine after irradiation. Caffeine also inhibited the rate at which incisions were mademore » and prolonged the time required to rejoin the discontinuities. Patch size, however, was unaffected by caffeine treatment.« less

Is initial excision of cutaneous melanoma by General Practitioners (GPs) dangerous? Comparing patient outcomes following excision of melanoma by GPs or in hospital using national datasets and meta-analysis.

Melanomas are initially excised in primary care, and rates vary internationally. Until now, there has been no strong evidence one way or the other that excising melanomas in primary care is safe or unsafe. European guidelines make no recommendations, and the United Kingdom (UK) melanoma guidelines require all suspicious skin lesions to be initially treated in secondary care based on an expert consensus, which lacks supporting evidence, that primary care excision represents substandard care. Despite this, studies have found that up to 20% of melanomas in the UK are excised by general practitioners (GPs). Patients receiving primary care melanoma excision may fear that their care is substandard and their long-term survival threatened, neither of which may be justified. Scottish cancer registry data from 9367 people diagnosed with melanoma in Scotland between 2005 and 2013 were linked to pathology records, hospital data and death records. A Cox proportional hazards regression analysis, adjusting for key confounders, explored the association between morbidity and mortality and setting of primary melanoma excision (primary versus secondary care). A pooled estimate of the relative hazard of death of having a melanoma excised in primary versus secondary care including 7116 patients from a similar Irish study was also performed. The adjusted hazard ratio (95% CI) of death from melanoma for those having primary care excision was 0.82 (0.61-1.10). Those receiving primary care excision had a median (IQR) of 8 (3-14) out-patient attendances compared to 10 (4-17) for the secondary care group with an adjusted relative risk (RR) (95% CI) of 0.98 (0.96-1.01). Both groups had a median of 1 (0-2) hospital admissions with an adjusted rate ratio of 1.05 (0.98-1.13). In the meta-analysis, with primary care as the reference, the pooled adjusted hazard ratio (HR, 95% CI) was 1.26 (1.07-1.50) indicating a significantly higher all-cause mortality among those with excision in secondary care. The results of the Scottish and pooled analyses suggest that those receiving an initial excision for melanoma in primary care do not have poorer survival or increased morbidity compared to those being initially treated in secondary care. A randomised controlled trial to inform a greater role for GPs in the initial excision of melanoma is justified in the light of these results. Copyright © 2017 Elsevier Ltd. All rights reserved.

Pre-Surgical Integration of fMRI and DTI of the Sensorimotor System in Transcortical Resection of a High-Grade Insular Astrocytoma

Herein we report on a patient with a WHO Grade III astrocytoma in the right insular region in close proximity to the internal capsule who underwent a right frontotemporal craniotomy. Total gross resection of insular gliomas remains surgically challenging based on the possibility of damage to the corticospinal tracts. However, maximizing the extent of resection has been shown to decrease future adverse outcomes. Thus, the goal of such surgeries should focus on maximizing extent of resection while minimizing possible adverse outcomes. In this case, pre-surgical planning included integration of functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI), to localize motor and sensory pathways. Novel fMRI tasks were individually developed for the patient to maximize both somatosensory and motor activation simultaneously in areas in close proximity to the tumor. Information obtained was used to optimize resection trajectory and extent, facilitating gross total resection of the astrocytoma. Across all three motor-sensory tasks administered, fMRI revealed an area of interest just superior and lateral to the astrocytoma. Further, DTI analyses showed displacement of the corona radiata around the superior dorsal surface of the astrocytoma, extending in the direction of the activation found using fMRI. Taking into account these results, a transcortical superior temporal gyrus surgical approach was chosen in order to avoid the area of interest identified by fMRI and DTI. Total gross resection was achieved and minor post-surgical motor and sensory deficits were temporary. This case highlights the utility of comprehensive pre-surgical planning, including fMRI and DTI, to maximize surgical outcomes on a case-by-case basis. PMID:27013996

Orbitopterional Approach for the Resection of a Suprasellar Craniopharyngioma: Adapting the Strategy to the Microsurgical and Pathologic Anatomy.

Objectives  To describe the orbitopterional approach for the resection of a suprasellar craniopharyngioma with emphasis on the microsurgical and pathological anatomy of such lesions. Design  After completing the orbitopterional craniotomy in one piece including a supraorbital ridge osteotomy, the Sylvian fissure was split in a distal to proximal direction. The ipsilateral optic nerve and internal carotid artery were identified. Establishing a corridor to the tumor through both the opticocarotid and optic cisterns allowed for a wide angle of attack. Using both corridors, a microsurgical gross total resection was achieved. A radical resection required transection of the stalk at the level of the hypothalamus. Photographs of the region are borrowed from Dr Rhoton's laboratory to illustrate the microsurgical anatomy. Understanding the cisternal and topographic relationships of the optic nerve, optic chiasm, and internal carotid artery is critical to achieving gross total resection while preserving normal anatomy. Participants  The surgery was performed by the senior author assisted by Dr. Jaafar Basma. The video was edited by Dr. Vincent Nguyen. Outcome Measures  Outcome was assessed with extent of resection and postoperative visual function. Results  A gross total resection of the tumor was achieved.

Improved understanding of how depot-specific adipose tissue mass predisposes to obesity-related comorbidities could yield new insights into the pathogenesis and treatment of obesity as well as metabolic benefits of weight loss. We hypothesized that three-dimensional contiguous “fat-water” MR imaging (FWMRI) covering the majority of a whole-body field of view (FOV) acquired at 3 Tesla (3T) and coupled with automated segmentation and quantification of amount, type and distribution of adipose and lean soft tissue would show great promise in body composition methodology. Precision of adipose and lean soft tissue measurements in body and trunk regions were assessed for 3T FWMRI and compared to DEXA. Anthropometric, FWMRI and DEXA measurements were obtained in twelve women with BMI 30–39.9 kg/m2. Test-retest results found coefficients of variation for FWMRI that were all under 3%: gross body adipose tissue (GBAT) 0.80%, total trunk adipose tissue (TTAT) 2.08%, visceral adipose tissue (VAT) 2.62%, subcutaneous adipose tissue (SAT) 2.11%, gross body lean soft tissue (GBLST) 0.60%, and total trunk lean soft tissue (TTLST) 2.43%. Concordance correlation coefficients between FWMRI and DEXA were 0.978, 0.802, 0.629, and 0.400 for GBAT, TTAT, GBLST and TTLST, respectively. While Bland Altman plots demonstrated agreement between FWMRI and DEXA for GBAT and TTAT, a negative bias existed for GBLST and TTLST measurements. Differences may be explained by the FWMRI FOV length and potential for DEXA to overestimate lean soft tissue. While more development is necessary, the described 3T FWMRI method combined with fully-automated segmentation is fast (<30 minutes total scan and post-processing time), noninvasive, repeatable and cost effective.

Flight-Path Characteristics for Decelerating From Supercircular Speed

NASA Technical Reports Server (NTRS)

Luidens, Roger W.

1961-01-01

Characteristics of the following six flight paths for decelerating from a supercircular speed are developed in closed form: constant angle of attack, constant net acceleration, constant altitude" constant free-stream Reynolds number, and "modulated roll." The vehicles were required to remain in or near the atmosphere, and to stay within the aerodynamic capabilities of a vehicle with a maximum lift-drag ratio of 1.0 and within a maximum net acceleration G of 10 g's. The local Reynolds number for all the flight paths for a vehicle with a gross weight of 10,000 pounds and a 600 swept wing was found to be about 0.7 x 10(exp 6). With the assumption of a laminar boundary layer, the heating of the vehicle is studied as a function of type of flight path, initial G load, and initial velocity. The following heating parameters were considered: the distribution of the heating rate over the vehicle, the distribution of the heat per square foot over the vehicle, and the total heat input to the vehicle. The constant G load path at limiting G was found to give the lowest total heat input for a given initial velocity. For a vehicle with a maximum lift-drag ratio of 1.0 and a flight path with a maximum G of 10 g's, entry velocities of twice circular appear thermo- dynamically feasible, and entries at velocities of 2.8 times circular are aerodynamically possible. The predominant heating (about 85 percent) occurs at the leading edge of the vehicle. The total ablated weight for a 10,000-pound-gross-weight vehicle decelerating from an initial velocity of twice circular velocity is estimated to be 5 percent of gross weight. Modifying the constant G load flight path by a constant-angle-of-attack segment through a flight- to circular-velocity ratio of 1.0 gives essentially a "point landing" capability but also results in an increased total heat input to the vehicle.

To examine the presence of features of sales promotion in cigarette advertising in United States magazines, and to describe trends in youth (ages 12-17) exposure to such advertising (termed "promotional advertising"). Analysis of 1980-1993 annual data on: (a) total pages and expenditures for "promotional advertising" (advertising that contains features of sales promotion) in 36 popular magazines (all magazines for which data were available), by cigarette brand; and (b) readership characteristics for each magazine. We defined promotional advertising as advertisements that go beyond the simple advertising of the product and its features to include one or more features of sales promotion, such as coupons, "retail value added" promotions, contests, sweepstakes, catalogues, specialty item distribution, and sponsorship of public entertainment or sporting events. Total pages of, and expenditures for promotional advertising in magazines; and gross impressions (number of readers multiplied by the number of pages of promotional advertising) among youth and total readership. During the period 1980-1993, tobacco companies spent $90.2 million on promotional advertising in the 36 magazines. The proportion of promotional advertising appearing in "youth" magazines (defined as magazines with a greater than average proportion of youth readers) increased from 7% in 1980 to nearly 100% in 1987. Although youth readers represented only 19% of magazine readers, the proportion of youth gross impressions to total gross impressions of tobacco promotional advertising exceeded this value throughout the entire period 1985-1993, peaking at 33% in 1987. The five "youth" cigarette brands (defined as brands smoked by at least 2.5% of smokers aged 10-15 years in 1993) accounted for 59% of promotional advertising in all magazines, but for 83% of promotional advertising in youth magazines during the study period. In their magazine advertising, cigarette companies are preferentially exposing young people to advertisements that contain sales promotional features.

To compare the effects of Roux-en-Y gastric bypass (RYGBP)procedures preserving different gastric volume on blood glucose of rats with non-obese type 2 diabetes. A total of 36 Goto-Kakizaki rats randomly underwent one of the following procedures: gastric bypass with different types of anastomosis including the Roux-en-Y of total stomach excision(n=12), the Roux-en-Y of partial stomach excision(n=12) and the Roux-en-Y of stomach preservation(n=12). Rats were observed for 24 weeks after surgery. Body weight, food intake and fasting blood glucose level were tested at 0(preoperative), 1, 3, 6, 12, 24 weeks. Hemoglobin A1c(HbA1c) level was measured at 0, 12, 24 weeks and glucose tolerance test (OGTT) was performed in conscious rats before (baseline) and then 30, 60, 120, and 180 minutes. Change of blood glucose over time was depicted. Area under curve(AUC) of glucose tolerance were calculated. Compared with preoperative levels, the weight and food intake of all the rats were significantly decreased at 1 week after surgery(P<0.01). At 3 weeks after operation, the weight and food intake were significantly increased compared with 1 week after operation in the Roux-en-Y of partial stomach excision and the Roux-en-Y of stomach retention(P<0.01). In the Roux-en-Y of total stomach excision, the weight and food intake were significantly lower compared with other two groups(P<0.05). At 24 weeks after operation, the levels of fasting blood glucose were (7.3 ± 1.5), (7.5 ± 2.0) and (8.3 ± 1.3) mmol/L, which were lower than the preoperative levels [(13.2 ± 1.6), (13.6 ± 2.5) and (12.9 ± 2.0) mmol/L, P<0.01] in the three groups. There were no significant differences among the three groups(P>0.05). At 24 weeks after operation, the HbA1c levels were(6.3 ± 1.3)%, (6.4 ± 2.0)% and (7.0 ± 1.3)%, which were lower than the preoperative level[(10.2 ± 2.6)%, (9.6 ± 2.5) and (9.9 ± 2.0)%, P<0.01]. There were no significant differences among the three groups(P>0.05). The trend of the glucose tolerance test and AUC were similar in the three groups after operation. Roux-en-Y gastric bypass in non-obese diabetic rats is effective in terms of glucose control and the efficacy of gastric bypass has no obvious association with the stomach volume.

Extramammary Paget's disease (EMPD) is a rare clinical entity and can be associated with other malignancies. We analyzed our experience for prognosis and impact of therapy on outcomes. We conducted a retrospective review of all patients (n = 33) with EMPD treated at a tertiary care center from 1971 to 1998. Pathologic features of EMPD, concurrent secondary malignancies, and the effect of operations on recurrence were analyzed. Overall survival was compared with that of the general population. Male-to-female ratio was 4:29, and median age was 70 years. Median followup was 68 months, and no patient died from EMPD. The lesion was predominantly found on the vulva (76%). Patch-like, nonconfluent growth was present in 45% of patients, and no patient had pathologic lymph nodes. The most common signs and symptoms were irritation or pruritus (73%) and rash (61%). The presence of patches, invasive tumor growth, or a second malignancy were significantly associated with a higher recurrence rate. The type of operation, either local excision or hemivulvectomy, was not related to the time to recurrence. Complete gross resection was achieved in 94% of cases. Fifty-six percent of patients had microscopically positive margin and this correlated with a significantly higher recurrence rate (p = 0.002). The tumor recurred clinically in 14 of 33 patients (42%) after a median of 152 months (range 5 to 209 months). In those patients, between one and six reexcisions were performed. In 14 of 33 patients with EMPD (42%), 16 concurrent secondary malignancies were found. Overall survival rates for EMPD patients were similar to those of the general population. EMPD is an infrequently diagnosed disease that is preferably managed with complete local excision and reexcisions if needed. A thorough search for frequently occurring secondary malignancies might be beneficial to provide the best outcomes for these patients. Copyright 2003 by the American College of Surgeons

Lymphocyte trafficking and HIV infection of human lymphoid tissue in a rotating wall vessel bioreactor

The pathogenesis of HIV infection involves a complex interplay between both the infected and noninfected cells of human lymphoid tissue, the release of free viral particles, the de novo infection of cells, and the recirculatory trafficking of peripheral blood lymphocytes. To develop an in vitro model for studying these various aspects of HIV pathogenesis we have utilized blocks of surgically excised human tonsils and a rotating wall vessel (RWV) cell culture system. Here we show that (1) fragments of the surgically excised human lymphoid tissue remain viable and retain their gross cytoarchitecture for at least 3 weeks when cultured in the RWV system; (2) such lymphoid tissue gradually shows a loss of both T and B cells to the surrounding growth medium; however, this cellular migration is reversible as demonstrated by repopulation of the tissue by labeled cells from the growth medium; (3) this cellular migration may be partially or completely inhibited by embedding the blocks of lymphoid tissue in either a collagen or agarose gel matrix; these embedded tissue blocks retain most of the basic elements of a normal lymphoid cytoarchitecture; and (4) both embedded and nonembedded RWV-cultured blocks of human lymphoid tissue are capable of productive infection by HIV-1 of at least three various strains of different tropism and phenotype, as shown by an increase in both p24 antigen levels and free virus in the culture medium, and by the demonstration of HIV-1 RNA-positive cells inside the tissue identified by in situ hybridization. It is therefore reasonable to suggest that gel-embedded and nonembedded blocks of human lymphoid tissue, cocultured with a suspension of tonsillar lymphocytes in an RWV culture system, constitute a useful model for simulating normal lymphocyte recirculatory traffic and provide a new tool for testing the various aspects of HIV pathogenesis.

Erosion of State Alcohol Excise Taxes in the United States.

2018-01-01

In the United States, excessive alcohol consumption is responsible for 88,000 deaths annually and cost $249 billion, or $2.05 per drink, in 2010. Specific excise taxes, the predominant form of alcohol taxation in the United States, are based on the volume of alcohol sold rather than a percentage of price and can thus degrade over time because of inflation. The objective of this study was to describe changes in inflation-adjusted state alcohol excise taxes on a beverage-specific basis. State-level data on specific excise taxes were obtained from the Alcohol Policy Information System and the Tax Foundation. Excise tax rates were converted into the tax per standard U.S. drink (14 g of ethanol) for beer, wine, and distilled spirits, and converted into 2015 dollars using annual Consumer Price Index data. Across U.S. states, the average state alcohol excise tax per drink in 2015 was $0.03 for beer, $0.05 for distilled spirits, and $0.03 for wine. From 1991 to 2015, the average inflation-adjusted (in 2015 dollars) state alcohol excise tax rate declined 30% for beer, 32% for distilled spirits, and 27% for wine. Percentage declines in state excise taxes since their inception were more than twice as large as those from 1991 to 2015. In 2015, average state specific excise taxes were $0.05 or less per standard drink across all beverage types and have experienced substantial inflation-adjusted declines.

The effects of a 5-week therapeutic horseback riding program on gross motor function in a child with cerebral palsy: a case study.

The purpose of this study was to determine the outcome of a short-term therapeutic horseback riding intervention on the gross motor function in a child with cerebral palsy. This study employed a repeated-measures design with a pretest, a post-test, and a post post-test conducted 5 weeks apart using the Gross Motor Function Measure (GMFM) as an outcome measure. The three sets of test scores from the GMFM were compared upon completion of the intervention. The subject participated in a 5-week therapeutic horseback riding program consisting of 1 hour of riding per week. Each riding session consisted of stretching, strengthening, and balance activities. The child's level of motor function was tested prior to the intervention, upon completion of the intervention, and 5 weeks postintervention. The GMFM, a criterion-referenced observational measure designed to measure change in the gross motor function in children with cerebral palsy, was chosen as the assessment tool. Upon completion of the 5-week intervention, the child was observed to have improved scores on the GMFM in two of the five dimensions measured and scored for a total of eight items. The post post-test was completed 5 weeks after the final riding session and the results demonstrated successful maintenance of the improved scores in seven of eight items. The result of this case study suggest that 5 weeks of therapeutic riding are sufficient to produce positive changes in the gross motor function of a child with cerebral palsy.

Little is known regarding gross motor skills (GMS) in children with idiopathic clubfoot (IC). This study describes GMS, specifically foot involvement and asymmetries, and analyses the association between GMS, gait, and foot status in children with IC. Gross motor tasks and gait were analyzed in children with IC and typically developed (TD) children. GMS were assessed using videotapes and the Clubfoot Assessment Protocol (CAP). The Gait Deviation Index (GDI) and GDI-Kinetic were calculated from gait analyses. Children were divided into bilateral, unilateral clubfoot, or TD groups. To analyze asymmetries, feet within each group were further classified into superior or inferior foot, depending on their CAP scores. Correlations identified associations between CAP and GDI, GDI-Kinetic, passive foot motion, and Dimeglio Classification Scores at birth in the clubfeet. In total, 75 children (mean age, 5 years) were enrolled (bilateral n=22, unilateral clubfoot n=25, TD=28). Children with clubfeet demonstrated significantly lower GMS, gait, and foot motion compared with TD children. One leg standing and hopping deviated in 84% and 91%, respectively, in at least one foot in children with clubfoot. Gross motor asymmetries were evident in both children with bilateral and unilateral involvement. In children with unilateral clubfoot, contralateral feet showed few deviations in GMS compared with TD; however, differences existed in gait and foot motion. The association between GMS and gait, foot motion, and initial foot status varied between poor and moderate. Gross motor deficits and asymmetries are present in children with both bilateral and unilateral IC. Development of GMS of the contralateral foot mirrors that of TD children, but modifies to the clubfoot in gait and foot motion. The weak association with gait, foot motion, and initial clubfoot severity indicates that gross motor measurements represent a different outcome entity in clubfoot treatment. We therefore, recommend gross motor task evaluation for children with IC.

Macroscopic Rotator Cuff Tendinopathy and Histopathology Do Not Predict Repair Outcomes of Rotator Cuff Tears.

Numerous studies have identified factors that may affect the chances of rotator cuff healing after surgery. Intraoperative tendon quality may be used to predict healing and to determine type of repair and/or consideration of augmentation. There are no data that correlate how gross tendon morphology and degree of tendinopathy affect patient outcome or postoperative tendon healing. Purpose/Hypothesis: The purposes of this study were to (1) compare the gross appearance of the tendon edge during arthroscopic rotator cuff repair with its histological degree of tendinopathy and (2) determine if gross appearance correlated with postoperative repair integrity. The hypothesis was that gross (macroscopic) tendon with normal thickness, no delamination, and elastic tissue before repair would have a correlation with low Bonar scores, higher postoperative American Shoulder and Elbow Surgeons (ASES) scores, and increased rates of postoperative tendon healing on ultrasound. Cross-sectional study; Level of evidence, 3. A total of 105 patients undergoing repair of medium-size (1-3 cm) full-thickness rotator cuff tears were enrolled in the study. Intraoperatively, the supraspinatus tendon was rated on thickness, fraying, and stiffness. Tendon tissue was recovered for histological analysis based on the Bonar scoring system. Postoperative ASES and ultrasound assessment of healing were obtained 1 year after repair. Correlation between gross appearance of the tendon and rotator cuff histology was determined. Of the 105 patients, 85 were followed the study to completion. The mean age of the patients was 61.6 years; Bonar score, 7.5; preoperative ASES score, 49; and postoperative ASES score, 86. Ninety-one percent of repairs were intact on ultrasound. Gross appearance of torn rotator cuff tendon tissue did not correlate with histological appearance. Neither histological (Bonar) score nor gross appearance correlated with multivariate analysis of ASES score, postoperative repair status, or demographic data. The degree of tendinopathy did not correlate with morphological appearance of the tendon. Neither of these parameters correlated with healing or patient outcome. This study suggests that the degree of tendinopathy, unlike muscle atrophy, may not be predictive of outcomes and that, on appearance, poor quality tendon has adequate healing capacity. Therefore, abnormal gross tendon appearance should not affect the repair effort or technique.

To evaluate the efficacy of combining preoperative immunosuppressive therapy with surgical excision for treatment of anal furunculosis (AF) in dogs. Retrospective study. Dogs (n=25) with stages 1-4 AF. Preoperative immunosuppressive therapy was either cyclosporine A (CyA) alone or in combination with ketoconazole (Group 1; n=18), or azathioprine combined with prednisolone (Group 2; n=7). Surgical excision of residual draining tracts, cryptectomy, and anal sacculectomy were performed. Only dogs with postoperative clinical follow-up exceeding 9 months were retained for the study. Both immunosuppressive protocols were effective in reducing progression of AF. Subsequent draining tracts excision, cryptectomy, and anal sacculectomy were bilateral (12 dogs) or unilateral (13 dogs of which 4 had bilateral anal sacculectomy). Postoperative recovery was uneventful, except for 2 dogs that had wound breakdown. Recurrence was not observed in any of the dogs that had bilateral surgical excision and or in 9 dogs that had unilateral excision. Preoperative immunosuppressive therapy, combined with bilateral surgical resection of affected tissue consistently, resulted in resolution of AF. Four dogs that had recurrence had unilateral excision despite initial bilateral involvement, suggesting that all diseased tissue should be excised. These preliminary results suggest that immunosuppressive therapy before surgical excision for AF yields minimizes recurrence in dogs.

Infrequent transposition of Ac in lettuce, Lactuca sativa.

Yang, C H; Ellis, J G; Michelmore, R W

1993-08-01

The maize transposable element Activator (Ac) is being used to develop a transposon mutagenesis system in lettuce, Lactuca sativa. Two constructs containing the complete Ac from the waxy-m7 locus of maize were introduced into lettuce and monitored for activity using Southern analysis and PCR amplification of the excision site. No transposition of Ac was detected in over 32 transgenic R1 plants, although these constructs were known to provide frequent transposition in other species. Also, no transposition was observed in later generations. In subsequent experiments, transposition was detected in lettuce calli using constructs that allowed selection for excision events. In these constructs, the neomycin phosphotransferase II gene was interrupted by either Ac or Ds. Excision was detected as the ability of callus to grow on kanamycin. Synthesis of the transposase from the cDNA of Ac expressed from the T-DNA 2' promoter resulted in more frequent excision of Ds than was observed with the wild-type Ac. No excision was observed with Ds in the absence of the transposase. The excision events were confirmed by amplification of the excision site by PCR followed by DNA sequencing. Excision and reintegration were also confirmed by Southern analysis. Ac/Ds is therefore capable of transposition in at least calli of lettuce.

To present a rare case of juvenile nasopharyngeal angiofibroma invading the ophthalmic orbit. The CT scan examination and the ultrasound tomography revealed the existence of a homogeneous solid mass causing distention and erosion of the nasal wall as well as dislocation of the ocular bulbus. The patient was operated, the mass was carefully liberated from its synechiae and it was totally excised with its capsule. A rare case of juvenile nasopharyngeal angiofibroma invading the orbit is presented. The tumor was totally excized and the patient is five years after the operation in good general health without recurrence of the tumor.

The aim of this study was to determine the frequency of invasive cancer found from specimens removed by surgical excision on patients with diagnosis of VIN 3. Seventy-eight patients with biopsy-proven vulvar intraepithelial neoplasia 3 (VIN 3) were treated by surgical excision. Sixteen patients (20.5%) were found to have invasion in the excised surgical specimen. Superficial invasion was seen in 7 patients (9%), 9 were noted to have >1 mm invasion (11.5%), and 1 patient had in situ Paget's disease (1.3%). Surgical excision should be considered a preferable method in management of patients with VIN 3. Copyright 1999 Academic Press.

The aim of this study is to evaluate the treatment outcome and analyze the associated factors of postoperative recurrence in patients who received transoral laser microsurgery for vocal cord leukoplakia. The demographic, histopathological data were retrospectively reviewed and the factors associated with recurrence of vocal leukoplakia after surgery were analyzed statistically. A total of 44 patients, including 36 males and 8 females, with a mean age of 50.4 ± 13.4 years, were enrolled. All the patients received excision of the vocal leukoplakia by carbon dioxide laser (2-4 Watt, ultrapulse mode) under general anesthesia. No patients had malignant transformation after surgery. Postoperative recurrence occurred in 10 patients (22.7 %). Univariate analysis showed that patients who had the habit of cigarette smoking, alcohol drinking, and presence of gastroesophageal reflux disease tended to recur. Among these risk factors, presence of gastroesophageal reflux disease (odds ratio 8.43) was the independent prognostic factor for recurrence using multivariate logistic regression analysis. Carbon dioxide laser excision is effective for treating vocal leukoplakia that is still confined to dysplasia of any degree, with acceptable morbidity. This study suggests that the presence of gastroesophageal reflux disease is the prognostic indicator for postoperative recurrence of vocal leukoplakia. Aggressive treatment of reflux disease for those who have received surgical excision for vocal leukoplakia is indicated.

Combining Magnetic Resonance Imaging (MRI) and Medical Infrared Thermography (MIT) in the pre- and per-operating management of severe Hidradenitis Suppurativa (HS).

Hidradenitis suppurativa (HS) is a chronic, inflammatory, and recurrent skin disease. Surgical excision of wounds appears to be the only curative treatment for the prevention of recurrence of moderate to severe stages. Magnetic resonance imaging (MRI) is a standard reference examination for the detection of HS peri-anal inflammatory fistula. In this case study, the use of real-time medical infrared thermography, in combination with MRI as appropriate imaging, is proposed. The aim is to assist surgeons in the pre- and peri-surgical management of severe perianal hidradenitis suppurativa with the intent to ensure that all diseased lesions were removed during surgery and therefore to limit recurrence. The results show that medical infrared thermography (MIT), coupled with MRI, could be highly effective strategy to address thermally distinguished health tissues and inflammatory sites during excision, as characterised by differential increases in temperature. Medical infrared thermography could be used to check the total excision of inflammatory lesions as a noninvasive method that is not painful, not radiant, and is easily transportable during surgery. Ultimately, this method could be complementary with MRI in providing clinicians with objective data on the status of tissues below the perianal skin surface in the pre- and per-operating management of severe hidradenitis suppurativa.

Thirty six patients with Paget's disease of the vulva were reviewed. The median age of the patients at diagnosis was 67 years (range: 45-91 years). One patient had a history of previous mammary adenocarcinoma. Screening for malignancy revealed two colonic tumours. Two patients with negative screening at presentation developed, 12 and 18 months respectively after vulvectomy, an ovarian carcinoma stage IIc and a cervical and urethral adenocarcinoma. All patients were treated by surgery based on extent of the disease. The operations performed included total vulvectomy (n = 11), partial vulvectomy (n = 14) and wide local excision (n = 4). Out of the 36 patients, 29 were available to follow-up. The median follow-up period was 74 months (range 2-204 months). Three patients died of metastatic disease due to vulval adenocarcinoma and breast carcinoma, or of liver metastases from an unknown adenocarcinoma. Eighteen of the 29 patients followed up remained free of disease. Five out of the 16 patients with positive margins recurred, as did 5 out of 9 patients with negative margins. Treatment of Paget's disease of the vulva is surgical. In order to prevent recurrence, some authors have proposed surgical excision extending beyond the visible clinical lesions with intraoperative frozen sections. The data we recorded show that free margins do not seem to correlate with recurrence, so that large excision beyond the clinical lesion is not useful.

Industry lobbying remains an obstacle to effective health-oriented alcohol policy. In 2013, an increase in excise tax on spirits was announced by the Polish government. This article presents a qualitative analysis of the public debate that ensued on the potential economic, health and social effects of the policy. It focuses on how competing groups, including industry actors, framed their position and sought to dominate the debate. Online archives of five Polish national newspapers, two spirits trade associations, and parliamentary and ministerial archives were searched. A thematic content analysis of the identified sources was conducted. The overall findings were compared with existing research on the framing of the Minimum Unit Pricing (MUP) debate in the UK. A total of 155 sources were analysed. Two main frames were identified: health, and economic. The spirits industry successfully promoted the economic frame in their own publications and in the media. The debate was dominated by arguments about potential growth of the grey market and losses in tax revenue that might result from the excise tax increase. The framing of the debate in Poland differed from the framing of the MUP debate in the United Kingdom. The Polish public health community was unsuccessful in making health considerations a significant element of the alcohol policy debate. The strategies pursued by UK health advocates offer lessons for how to make a more substantial impact on media coverage and promote health-oriented legislation.

Two case reports of telangiectatic osteosarcoma treated with complete segmental resection of the spine, including the spinal cord. To report the en bloc tumor excision, including the spinal cord, for telangiectatic osteosarcoma, and discuss the indication of cord transection and influence after cutting the spinal cord. To our knowledge, there are no previous reports describing telangiectatic osteosarcoma of the spine and the subsequent en bloc excision of the spine, including the spinal cord. The clinical and radiographic presentations of 2 cases with telangiectatic osteosarcoma are presented. Because these 2 cases already had complete paralysis for at least 1 month, it was suspected that there was no possibility of recovering spinal cord function. Complete segmental spinal resection (total en bloc spondylectomy) was performed. At that level, the spinal cord was also cut and resected. En bloc excision of the tumor with a wide margin was achieved in both cases. In the resected specimen, the nerve cells in the spinal cord had lapsed into degenerative necrosis. The pathologic findings showed that there was no hope for recovery of spinal cord function. En bloc spinal resection, including the spinal cord, is an operation allowed when there is no hope for recovery of spinal cord function. This surgery should be accepted as an option in spine tumor surgeries.

The effect of alcoholic beverage excise tax on alcohol-attributable injury mortalities.

This study examines the effect of state excise taxes on different types of alcoholic beverages (spirits, wine, and beer) on alcohol-attributable injury mortalities--deaths caused by motor vehicle accidents, suicides, homicides, and falls--in the United States between 1995 and 2004, using state-level panel data. There is evidence that injury deaths attributable to alcohol respond differently to changes in state excise taxes on alcohol-specific beverages. This study examines the direct relationship between injury deaths and excise taxes without testing the degree of the association between excise taxes and alcohol consumption. The study finds that beer taxes are negatively related to motor vehicle accident mortality, while wine taxes are negatively associated with suicides and falls. The positive coefficient of the spirit taxes on falls implies a substitution effect between spirits and wine, suggesting that an increase in spirit tax will cause spirit buyers to purchase more wine. This study finds no evidence of a relationship between homicides and state excise taxes on alcohol. Thus, the study concludes that injury deaths attributable to alcohol respond differently to the excise taxes on different types of alcoholic beverages.

In 2014, SSO-ASTRO published guidelines which recommended "no ink on tumor" as adequate margins for patients undergoing breast conservation for invasive breast cancer. In 2016, new SSO-ASTRO-ASCO guidelines recommended 2 mm margins for DCIS. We evaluated whether these guidelines affected re-excision rates at our institution. Patients treated with breast conservation surgery from January 1, 2010-March 1, 2016 were identified. Re-excision rates, tumor characteristics, and presence of residual disease were recorded. The 2016 guidelines were retrospectively applied to the same cohort and expected re-excision rates calculated. Re-excision rates did not significantly decline before and after 2014 guideline adoption (11.9% before, 10.9% after; p = 0.65) or when the 2016 guidelines were retrospectively applied (8.4%; p = 0.10). The 2014 and 2016 guidelines had minimal impact on our re-excision rates, as most re-excisions were done for DCIS and 2016 guidelines supported our prior institutional practices of 2 mm margins for these patients.

The goal of this study was to quantify the economic role of dairy farming in New Mexico and to identify its linkages with allied industries in terms of income, value added, and employment impacts. An input-output model was used to estimate the direct, indirect, and induced impacts of the dairy farm industry on the economy of New Mexico. The results showed that in 2005, New Mexico's dairy farm industry had a total economic impact of $1.98 billion and accounted for 14,313 jobs. Therefore, dairy farming in New Mexico had an output multiplier (income) of 1.92, a labor income multiplier of $248 thousand/$ million of gross sales, and an employment multiplier of 13.91 jobs/$ million of gross sales. Furthermore, the New Mexico dairy farms accounted for 13.1% of the total agricultural outputs, 20.5% of the agricultural jobs, 1.5% of total state economic activity, and $80 million in tax revenue. With the exception of Lea, Eddy, and Bernalillo counties, which are diversified, the dairy farms accounted for more than two-thirds of the agricultural outputs and for more than two-fifths of the agricultural employment in counties where dairy farms are concentrated.

Environmental characteristics within preschools that influence children's motor competence are largely unknown. The purpose of the present study was to examine the contribution of various preschool environmental characteristics to children's locomotor, object control, and total gross motor scores. Cross-sectional, observational study of 3-5 year-old children (n=229) from 22 preschools in South Carolina. The Children's Activity and Movement in Preschool Study (CHAMPS) Motor Skills Protocol assessed MC. Preschool directors provided information regarding policies and practices. The research team measured playgrounds and classrooms, and the Early Childhood Environment Rating Scale-Revised assessed preschool quality. Time spent in open space and electronic media use were also assessed using direct observation. The aforementioned variables predicted children's object control, locomotor, and total gross motor scores. Classroom size/child ratio, teacher education, playground size, electronic media use, and trips to outside organizations emerged as significant predictors of locomotor score and total motor score. The object control model was non-significant. Preschools may be able to promote motor competence by allowing children more time in open spaces, structured activity experiences, and by expanding existing outdoor playground space whenever possible.

Smoke inhalation injury frequently increases the risk of pneumonia and mortality in burn patients. The pathophysiology of acute lung injury secondary to burn and smoke inhalation is well studied, but long-term pulmonary function, especially the process of lung tissue healing following burn and smoke inhalation, has not been fully investigated. By contrast, early burn excision has become the standard of care in the management of major burn injury. While many clinical studies and small-animal experiments support the concept of early burn wound excision, and show improved survival and infectious outcomes, we have developed a new chronic ovine model of burn and smoke inhalation injury with early excision and skin grafting that can be used to investigate lung pathophysiology over a period of 3 weeks. Materials and methods Eighteen female sheep were surgically prepared for this study under isoflurane anesthesia. The animals were divided into three groups: an Early Excision group (20% TBSA, third-degree cutaneous burn and 36 breaths of cotton smoke followed by early excision and skin autografting at 24 h after injury, n = 6), a Control group (20% TBSA, third-degree cutaneous burn and 36 breaths of cotton smoke without early excision, n = 6) and a Sham group (no injury, no early excision, n = 6). After induced injury, all sheep were placed on a ventilator and fluid-resuscitated with Lactated Ringers solution (4 mL/% TBS/kg). At 24 h post-injury, early excision was carried out to fascia, and skin grafting with meshed autografts (20/1000 in., 1:4 ratio) was performed under isoflurane anesthesia. At 48 h post-injury, weaning from ventilator was begun if PaO2/FiO2 was above 250 and sheep were monitored for 3 weeks. Results At 96 h post-injury, all animals were weaned from ventilator. There are no significant differences in PaO2/FiO2 between Early Excision and Control groups at any points. All animals were survived for 3 weeks without infectious complication in Early Excision and Sham groups, whereas two out of six animals in the Control group had abscess in lung. The percentage of the wound healed surviving area (mean ± SD) was 74.7 ± 7.8% on 17 days post-surgery in the Early Excision group. Lung wet-to-dry weight ratio (mean ± SD) was significantly increased in the Early Excision group vs. Sham group (p < 0.05). The calculated net fluid balance significantly increased in the early excision compared to those seen in the Sham and Control groups. Plasma protein, oncotic pressure, hematocrit of % baseline, hemoglobin of % baseline, white blood cell and neutrophil were significantly decreased in the Early Excision group vs. Control group. Conclusions The early excision model closely resembles practice in a clinical setting and allows long-term observations of pulmonary function following burn and smoke inhalation injury. Further studies are warranted to assess lung tissue scarring and measuring collagen deposition, lung compliance and diffusion capacity. PMID:22459154

Biopsies and surgical excisions represent routine procedures in clinical settings dealing with skin cancer. To evaluate the impact of clinical examination, dermoscopy, reflectance confocal microscopy and digital monitoring on the decision to excise or biopsy a lesion in routine practice. Patients scheduled for biopsy or excision of a skin lesion were prospectively enrolled. The expert dermatologist was asked to select the main factor that prompted him/her to excise or biopsy the lesion. The most common reason for melanoma excision was clinical and dermoscopic morphology (70.3%), followed by dermoscopy (11.4%), monitoring (8.9%) and clinical context (8.2%). Most basal and squamous cell carcinomas were recognized both clinically and dermoscopically, while 18.6 and 15.0%, respectively, could only be detected with dermoscopic examination. Each part of the clinical examination has a contributory role in the diagnosis of melanoma and other skin cancers.

En bloc excision of a dermal sinus tract.

Dermal sinus tracts are a form of spinal dysraphism that arises from a failure of dysjunction early in embryogenesis. They are diagnosed in pediatric patients and who present with a dimple, infection, or neurologic deficit. The tract is surgically excised en bloc to avoid contamination from the tract, which harbors bacteria. However, dermal sinus tracts typically terminate intradurally, rendering their en bloc excision difficult. To avoid entering the tract, allowing for an en bloc excision, we modified the usual technique employed for accessing the spinal intradural space. An en bloc excision of the dermal sinus tract was successfully performed. The patient recovered from the procedure neurologically intact and her postoperative course was uncomplicated. We conclude that en bloc excision of a dermal sinus tract down to the intradural space is feasible with modifications to standard operative technique. Copyright © 2010 Elsevier Ltd.

Although many methods have been developed to treat ear keloids, new therapeutic options are still needed. To determine the effects of topical mitomycin C (MC) on shave-removed wounds and fibroblasts of ear keloids. Fourteen ear keloids in 12 patients were shaved, and MC (1 mg/mL) was applied to the resected bed for 5 minutes. The application was repeated 3 weeks later. All patients were assessed 2, 4, and 6 months after the procedure to evaluate the cosmetic results, recurrence, and postsurgical complications. An in vitro study to determine the effects of MC on fibroblasts of the excised keloids was conducted using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, the measurement of total cell counts, and immunoassay of DNA synthesis. Only one recurrence occurred (on the ear helix), and the patients were satisfied with the cosmetic outcomes. The results of the MTT assay, total cell counts, and DNA synthesis immunoassay confirmed the suppressive effects of MC on the keloid fibroblasts. The application of topical MC to the resected bed of shave-removed ear keloids was successful in preventing recurrences and providing an acceptable cosmetic outcome. © 2011 by the American Society for Dermatologic Surgery, Inc.

The potential contribution of psychological and anatomical changes to sexual dysfunction in female patients following short-term preoperative radiotherapy (5 x 5 Gy) and total mesorectal excision (TME) is not clear. Aim. In this study we assessed female sexual dysfunction in patients who underwent radiotherapy and TME for rectal cancer. Genital arousal was assessed using vaginal videoplethysmography. Sexual functioning was examined in four patients who had rectal cancer and underwent radiotherapy and TME. All investigations were done at least 15 months after treatment. The results were compared with an age-matched group of 18 healthy women. The patients and healthy controls showed comparable changes in vaginal vasocongestion during sexual arousal, though three out of four patients showed a lower mean spectral tension (MST) of the vaginal pulse compared with healthy controls. Subjective sexual arousal was equivalent between the two groups. In this study the changes of genital and subjective sexual arousal after erotic stimulus condition between patients and healthy controls were not different, though lower MST of the vaginal pulse was found in three out of four patients compared with healthy women. Additional work, however, must be performed to clarify the mechanisms of sexual dysfunction following treatment of rectal cancer.

Solitary spinal epidural cavernous angiomas are rare vascular malformations. Surgical excision is the treatment of choice, as these lesions tend to grow or bleed at some point. In this 3-dimensional, narrated video, we present the case of a 61-year-old male who presented with progressive pain in the right paravertebral region secondary to an epidural cavernous angioma located at the T6/T7 level. Under intraoperative neurophysiological monitoring, a laminectomy between T5 and T7 was performed. A reddish, well delimited, and highly vascularized epidural mass was identified and dissected from the adjacent dura and nerve root, and an en bloc total resection was achieved. The patient was discharged neurologically intact on postoperative day 4, presenting a remarkable improvement of his pain at 2-month follow-up. Total excision of these lesions is possible in most of cases, remaining the standard treatment, with minimum complications. All procedures were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards. All data related to patient identification were removed from this surgical video and manuscript, with no need of a written informed consent.

Reliability and responsiveness of the gross motor function measure-88 in children with cerebral palsy.

PubMed

Ko, Jooyeon; Kim, MinYoung

2013-03-01

The Gross Motor Function Measure (GMFM-88) is commonly used in the evaluation of gross motor function in children with cerebral palsy (CP). The relative reliability of GMFM-88 has been assessed in children with CP. However, little information is available regarding the absolute reliability or responsiveness of GMFM-88. The purpose of this study was to determine the absolute and relative reliability and the responsiveness of the GMFM-88 in evaluating gross motor function in children with CP. A clinical measurement design was used. Ten raters scored the GMFM-88 in 84 children (mean age=3.7 years, SD=1.9, range=10 months to 9 years 9 months) from video records across all Gross Motor Function Classification System (GMFCS) levels to establish interrater reliability. Two raters participated to assess intrarater reliability. Responsiveness was determined from 3 additional assessments after the baseline assessment. The interrater and intrarater intraclass correlation coefficients (ICCs) with 95% confidence intervals, standard error of measurement (SEM), smallest real difference (SRD), effect size (ES), and standardized response mean (SRM) were calculated. The relative reliability of the GMFM was excellent (ICCs=.952-1.000). The SEM and SRD for total score of the GMFM were acceptable (1.60 and 3.14, respectively). Additionally, the ES and SRM of the dimension goal scores increased gradually in the 3 follow-up assessments (GMFCS levels I and II: ES=0.5, 0.6, and 0.8 and SRM=1.3, 1.8, and 2.0; GMFCS levels III-V: ES=0.4, 0.7, and 0.9 and SRM=1.5, 1.7, and 2.0). Children over 10 years of age with CP were not included in this study, so the results should not be generalized to all children with CP. Both the reliability and the responsiveness of the GMFM-88 are reasonable for measuring gross motor function in children with CP.

Comparing motor performance, praxis, coordination, and interpersonal synchrony between children with and without Autism Spectrum Disorder (ASD).

Kaur, Maninderjit; M Srinivasan, Sudha; N Bhat, Anjana

Children with Autism Spectrum Disorder (ASD) have basic motor impairments in balance, gait, and coordination as well as autism-specific impairments in praxis/motor planning and interpersonal synchrony. Majority of the current literature focuses on isolated motor behaviors or domains. Additionally, the relationship between cognition, symptom severity, and motor performance in ASD is unclear. We used a comprehensive set of measures to compare gross and fine motor, praxis/imitation, motor coordination, and interpersonal synchrony skills across three groups of children between 5 and 12 years of age: children with ASD with high IQ (HASD), children with ASD with low IQ (LASD), and typically developing (TD) children. We used the Bruininks-Oseretsky Test of Motor Proficiency and the Bilateral Motor Coordination subtest of the Sensory Integration and Praxis Tests to assess motor performance and praxis skills respectively. Children were also examined while performing simple and complex rhythmic upper and lower limb actions on their own (solo context) and with a social partner (social context). Both ASD groups had lower gross and fine motor scores, greater praxis errors in total and within various error types, lower movement rates, greater movement variability, and weaker interpersonal synchrony compared to the TD group. In addition, the LASD group had lower gross motor scores and greater mirroring errors compared to the HASD group. Overall, a variety of motor impairments are present across the entire spectrum of children with ASD, regardless of their IQ scores. Both, fine and gross motor performance significantly correlated with IQ but not with autism severity; however, praxis errors (mainly, total, overflow, and rhythmicity) strongly correlated with autism severity and not IQ. Our study findings highlight the need for clinicians and therapists to include motor evaluations and interventions in the standard-of-care of children with ASD and for the broader autism community to recognize dyspraxia as an integral part of the definition of ASD.

Comparison of methods for estimating the cost of human immunodeficiency virus-testing interventions.

2012-01-01

The Centers for Disease Control and Prevention (CDC), Division of HIV/AIDS Prevention, spends approximately 50% of its $325 million annual human immunodeficiency virus (HIV) prevention funds for HIV-testing services. An accurate estimate of the costs of HIV testing in various settings is essential for efficient allocation of HIV prevention resources. To assess the costs of HIV-testing interventions using different costing methods. We used the microcosting-direct measurement method to assess the costs of HIV-testing interventions in nonclinical settings, and we compared these results with those from 3 other costing methods: microcosting-staff allocation, where the labor cost was derived from the proportion of each staff person's time allocated to HIV testing interventions; gross costing, where the New York State Medicaid payment for HIV testing was used to estimate program costs, and program budget, where the program cost was assumed to be the total funding provided by Centers for Disease Control and Prevention. Total program cost, cost per person tested, and cost per person notified of new HIV diagnosis. The median costs per person notified of a new HIV diagnosis were $12 475, $15 018, $2697, and $20 144 based on microcosting-direct measurement, microcosting-staff allocation, gross costing, and program budget methods, respectively. Compared with the microcosting-direct measurement method, the cost was 78% lower with gross costing, and 20% and 61% higher using the microcosting-staff allocation and program budget methods, respectively. Our analysis showed that HIV-testing program cost estimates vary widely by costing methods. However, the choice of a particular costing method may depend on the research question being addressed. Although program budget and gross-costing methods may be attractive because of their simplicity, only the microcosting-direct measurement method can identify important determinants of the program costs and provide guidance to improve efficiency.
